2025-04-14T21:04:03+03:00

To perform a comprehensive analysis of the technological features of the construction of large-span coatings, twelve completed projects were selected. Investigated variants for the construction of reinforced concrete or metal coatings were divided into four groups according to the criterion of using methods of free or forced lifting (movement) in installation processes. To perform calculations of installation and technological indicators of the erection of roofing structures, data on the movement of coating segments in horizontal and vertical planes were used between the areas of storage, pre-lifting and lifting to the design height. Also, the indicators of the duration of the processes of pre-lifting enlargement and lifting the segments of coatings to the design levels were used. The values of the total speed of installation processes, the total productivity of the installation team involved in the processes of coating erection and indicators of the total complexity of installation are displayed in the table and on the histograms. A comparative analysis of the indicators of installation technology indicates that the options for erecting segments of coatings using free lifting methods using crane technologies are significantly inferior to the options for erecting blocks of coatings of 100% readiness using crane-free technologies. The most effective among the options for forced movement of coatings were solutions using vertical guides or growing columns. The use of vertical guides or growing columns allows to compose the zones of storage, pre-lifting enlargement and lifting of coatings within a site that does not exceed the dimensions of the coating being mounted. The possibility of performing the entire complex of works on the construction of large-sized buildings in areas whose dimensions do not exceed the dimensions of the coating being mounted is a very relevant argument when developing structural and technological solutions for the construction of new and reconstruction, damaged by the ongoing war, of objects in conditions of dense development.

Stability of the shell of the minimum surface on a trapezoidal contour, taking into account geometric nonlinearity under thermal and power loading

2025-04-14T21:24:08+03:00

For the calculation of spatial thin-walled structures, it is necessary to perform verification calculations for two groups of limit states. The first group of limit states includes strength and stability calculations. The second group of limit states includes deflection and crack resistance calculations.

The object of study is a shell of minimal surface on a trapezoidal contour, which is a thin-walled spatial structure. This type of shell is used in the following industries: mechanical engineering, chemical industry, aircraft construction, and drone construction. They have high strength, rigidity and lightness, and are easy to manufacture.

The shells of minimal surfaces, which are studied by traditional methods of mathematical physics, are not sufficiently studied due to the unique thin-walled structures that were derived by optimizing the shape on a given contour. Recently, the creation of advanced structures, high-performance machines and special-purpose objects often leads to the need to develop structural shell elements with a complex geometric structure - which are the shells of minimal surfaces.

The essence of the geometrically nonlinear formulation is to find the actual displacements of the finite element model when studying the loss of global stability of the shell of the minimum surface on a trapezoidal contour, as well as to find the special places where the actual loss of stability occurs on the mid-surface. This methodology allows to calculate the loss of stability of the minimum surface shell with a high enough accuracy, which leads to the optimization of stability in multi-criteria parametric optimization.

Numerical studies were carried out using the finite element method (FEM). After creating the finite element model, a combination of external loads was set in accordance with the building codes of Ukraine. Next, an initial stability calculation was performed, which showed that the first four forms of stability loss have a strain energy coefficient of less than one. The thickness of the shell of the minimum surface on the trapezoidal contour was selected as follows, the minimum strain energy on the first form of loss of stability was a factor of 1.0, while the required thickness was 36 mm.

Based on the analyzed elements of the influence of organizational and technological factors on the construction industry, it was found that traditional construction has exceptionally high indicators of reliability, durability, stability, etc., but at the same time it is inferior to modular construction of buildings and structures in terms of time and resource consumption, environmental impact, as well as in rapid adaptation to the special challenges of today, of a social or natural nature, etc., which makes the use of modular technologies one of the leading phenomena in the construction sector.

Determination of reinforcement depth for low-energy dynamic compaction construction in high-fill engineering in mountainous areas

2025-04-14T21:32:49+03:00

Dynamic compaction technology has gained rapid development and widespread application in soft soil reinforcement due to its numerous advantages. This study investigates low-energy dynamic compaction commonly used in high-fill mountain engineering, detailing its construction processes and engineering applications while systematically reviewing current theories and advancements in determining reinforcement zones. However, existing methods for defining effective reinforcement depth still rely heavily on construction experience and trial section testing, resulting in cumbersome procedures, high data dispersion, and insufficient reliability. To address this, the authors established a clear distinction between "effective reinforcement depth" and "influence depth of reinforcement" based on the "ellipsoidal morphology" assumption. Starting from the principle of equal soil mass before and after compaction (neglecting air mass), a complete set of calculation formulas for both depths was derived. The derivation process incorporated both compaction parameters (e.g., energy level, tamping frequency) and intrinsic soil properties (e.g., initial density, Poisson’s ratio). These formulas enable efficient computation of reinforcement depths when inputting known parameters, offering a novel approach to evaluate reinforcement effectiveness and optimize compaction strategies for low-energy projects. Furthermore, a series of low-energy dynamic compaction tests with varying energy levels were designed and implemented in a northwestern Chinese high-fill project. Field measurements of single-blow and cumulative settlements, effective reinforcement depths, and influence depths were collected and compared with formula-calculated results, confirming the formulas’ accuracy and engineering reliability. The methodology and outcomes provide a research paradigm for similar projects and enrich the theoretical basis for evaluating soft soil reinforcement using dynamic compaction technology.

Research on the influencing factors of energy consumption of rural residential buildings in severe cold areas

2025-04-14T21:38:01+03:00

Energy consumption of rural residential buildings was a key issue addressed in global sustainable development efforts. In this study, a typical rural self-built house in the severely cold climate of Jiuquan, China, was selected, and a dynamic energy consumption model was established using DesignBuilder software. The model was used to systematically analyze how six factors – building orientation, storey height, window-to-wall ratio, facade construction, roof construction, and external window materials-affected heating energy consumption through a one-factor experiment and an L25(5^6) orthogonal test. The results revealed that external wall insulation performance played the most significant role in energy consumption regulation, with EPS insulation facades saving 20.4% more energy than traditional clay brick walls. Low-E coated heat-breaking aluminum windows reduced energy consumption by 18.3% compared to single-pane wood frame windows, and using a 100 mm XPS insulation roof saved 9.8% of energy. The sensitivity ranking showed that the thermal parameters of the envelope (facade > windows > roof) had a stronger influence than building form parameters (floor height > window-to-wall ratio > orientation). The optimal combination scheme (WA4+WI5+RO5) achieved an annual energy consumption of 27,707 kWh, a 24.3% reduction from the baseline model. The study proposed a synergistic design strategy prioritizing high-performance envelope retrofits while limiting incremental storey heights and window-to-wall ratios, providing a quantitative basis for locally adapted energy efficiency policies for rural buildings.

The concept of strategic investment management is proposed, which involves the creation of an integrated system for assessing investment priorities based on a combination of financial, technological and socio-economic factors. This approach ensures optimal allocation of resources, helps to increase the financial stability of enterprises and minimizes the risks of ineffective investment.

The results of the study can be useful for a wide range of participants in the construction market, including investors, developers, financial institutions and state regulators. The use of the proposed methodological approaches will increase the level of validity of investment decisions and contribute to the formation of a sustainable investment strategy in the construction sector.

Justification of the components of a digitalized energy consumption control toolkit for contracting enterprises

2025-04-15T20:47:53+03:00

This article addresses the issue of managing energy efficiency in construction production for contracting enterprises, which arises due to the gaps between periods of energy resource consumption and the inflow of financial resources for their payment. It has been determined that traditional methods of assessing payment capacity deficits do not provide a well-founded answer regarding the financial and energy security of construction enterprises. Given this, the article proposes conceptual foundations for designing intelligent energy consumption control systems for contracting enterprises, considering the formation of financial capabilities to cover expenditures on energy carriers and electricity.

Based on cost-estimating norms in construction, indicator variables have been justified, the variation of which serves as a basis for strengthening energy consumption control. Threshold values have been determined, where approaching them indicates the advisability or inadvisability of revising the energy intensity policy of construction production and its organization. The dynamics of resource consumption have been studied in accordance with the substantiated technological methods of performing construction works. It has been found that energy consumption growth is not uniform but depends on partial increases in the estimated cost of materials, construction, and the normatively calculated labor intensity.

The practical feasibility of applying quantitative indicator values using traditional mathematical statistics methods, particularly k-means clustering, has been proven. A detailed argument is provided in favor of using fuzzy set theory methods for energy consumption management in construction, specifically: membership functions, their types, quantity, and parameters; logical connections and structures; as well as the application of fuzzy logical statements.

The results of research aimed at justifying the components of a digitalized control toolkit are summarized in a comprehensive five-stage algorithm suitable for use by economic department specialists or management personnel without specialized IT project design education. At the same time, the obtained results hold significant scientific and practical potential for the development of artificial intelligence systems capable of managing energy consumption in contracting enterprises based on fuzzy logic and machine learning.

Substitution of the significance of the choice of a design solution and its impact on the total cost of the life cycle of a construction object

2025-04-15T20:53:34+03:00

The article examines in detail the process of optimizing production solutions related to the arrangement of floor coverings from various materials, including plank flooring, parquet floors, floors made of wooden panels and wooden boards. Particular attention is paid to the economic analysis of the choice of constructive and technological solutions in order to minimize costs and increase the efficiency of using available resources. To determine the optimal option for performing the work, the linear programming method was used, which allows taking into account numerous variables and restrictions.

As part of the study, an objective function was formulated that reflects the maximization of profit from the performance of construction work. In addition, a system of constraints was developed that takes into account the available labor, material and technical resources, as well as the project implementation timeframe. Calculations were carried out using the simplex method, which made it possible to determine the optimal resource allocation plan and minimize costs at each stage of construction work.

According to the results of the study, the best solution is to use chipboard for arranging floor coverings. This option has the highest desirability index, which indicates its superiority over other materials. Chipboard is also a competitive option. Board coverings and fiberboard bases, in turn, have lower desirability indices due to high costs and rapid wear. The results obtained can be used in construction design practice to make economically sound decisions that will contribute to increasing the total life cycle cost of construction projects. This will allow construction companies not only to reduce costs, but also to increase competitiveness in the market, offering customers more effective and cost-effective solutions.

Research on a specially developed and improved system for evaluating investment projects for reconstruction and restoration of the housing stock as an important element of social protection of the population. The author analyzes modern approaches to evaluating investment projects in the field of new construction, reconstruction, modernization, housing and communal services, identifies their advantages and disadvantages and offers an improved methodology that takes into account socio-economic factors and covers the interests of different population groups.

The article examines the main problems of depreciation of the housing stock, the need for its modernization and reconstruction, and also justifies the significance of investments in this sector from the point of view of ensuring decent living conditions and social security. The author emphasizes the importance of implementing a comprehensive evaluation system that affects financial indicators, social aspects and the environmental component, which meets the principles of sustainable development.

The proposed methodology is based on multi-criteria analysis, which allows reducing not only the economic efficiency of the project, but also its social impact, the availability of housing for different categories of the population and improving the quality of life of residents. Particular attention is paid to assessing the risks associated with the implementation of investment projects and developing mechanisms to minimize these risks.

It is signed that the implementation of a system for evaluating investment projects for the reconstruction of the housing stock will contribute to increasing the effectiveness of state policy in the field of social protection, attracting private investment and creating favorable conditions for the modernization of the housing sector. The article contains practical recommendations for improving the regulatory framework and mechanisms of state regulation in this area, as well as approaches to ensuring transparency and objectivity of the evaluation process.

Thus, the proposed assessment system is a tool that allows ensuring balanced development of housing infrastructure, improving the quality of housing conditions and strengthening social protection of the population through effective planning and implementation of investment projects for the reconstruction of the housing stock.

Life-Cycle Cost Assessment of Real Estate Assets: Ukrainian Realities and International Experience, Challenges and Prospects

2025-04-20T22:15:47+03:00

This article explores the theoretical foundations and practical aspects of applying the concepts of Life-Cycle Costing (LCC) and Whole-Life Costing (WLC) to assess the economic efficiency of investments in the construction and operation of real estate assets. In the context of economic instability, inflationary pressures, energy crises, and the growing need for resource efficiency, the relevance of approaches that account not only for construction phase expenditures but also for costs incurred throughout the entire life cycle of an asset is significantly increasing.

The study examines the features of the national regulatory approach, with a focus on the provisions of the Ukrainian standard DSTU ISO 15686-5:2020, which establishes methodological foundations for LCC assessment. The key barriers to the implementation of LCC and WLC methods in Ukraine are identified as insufficient regulatory support, low awareness among market participants, a lack of standardized tools for economic calculations, and an underdeveloped culture of long-term financial planning in the construction sector.

A comparative analysis of the LCC and WLC concepts is presented. LCC is primarily focused on expenditures associated with design, construction, operation, maintenance, and disposal, while WLC also accounts for externalities, social and environmental factors, including asset residual value and environmental impact costs. This distinction is particularly relevant in the context of the EU’s sustainable construction priorities and Ukraine’s post-war reconstruction.

The article discusses international experience in integrating LCC/WLC approaches into project management practices as a positive reference point for the Ukrainian construction industry. The feasibility of implementing life-cycle assessment mechanisms in the planning of public and private construction projects is substantiated, with the aim of improving investment efficiency, reducing energy consumption, increasing procurement transparency, and establishing an effective value management system throughout an asset's service life.

The paper also outlines future research directions, including the digitalization of LCC/WLC calculations (particularly integration with BIM technologies), the development of national industry-specific databases on maintenance and repair costs, and the advancement of tools for comparative analysis of project alternatives based on life-cycle principles. It is emphasized that the implementation of LCC and WLC concepts has the potential not only to reduce costs but also to achieve broader socio-economic and environmental goals in real estate management. The need to integrate social and behavioral dimensions into life-cycle assessment (LCA) methodologies for construction assets is also underlined.
