The study constructs a comprehensive evaluation model of industrial heritage urban landscape ecology, researches each index affecting landscape ecology, and determines the weight of each influence index by combining qualitative and quantitative methods. The maximum influence factors of the four criteria layers of emotion, culture, material and ecology are pleasure, obvious cultural symbols, appropriate scale and microclimate regulation, and the corresponding values are 0.313, 0.404, 0.315 and 0.495, respectively. Compared with that before the introduction of the self-organised neural network fusion K-Means clustering algorithm, the ecological evaluation scores of the urban landscape of the industrial heritage are much closer to the real situation, and the overall error is much higher. The ecological evaluation model of industrial heritage buildings is closer to the real situation, and the overall error fluctuation is 0.012-0.020. The precision-recall curve of the comprehensive evaluation model of industrial heritage buildings is more advantageous than that of other comprehensive evaluation models. The results of the study provide a scientific reference basis for the design of the external landscape environment of industrial heritage buildings, and provide a strong scientific support for the ecological symbiosis between old industrial buildings and the environment under the concept of sustainability.

    29-42页
    查看更多>>摘要：In recent years, virtual reality technology has been widely applied and researched in various fields. In digital architectural design and simulation, it has gradually become an important tool. For the evacuation of commercial buildings, virtual reality technology is introduced and a digital building evacuation simulation model based on panic emotions is proposed. Meanwhile, based on this model, the behavior and distribution of pedestrians are simulated, targeted evacuation design schemes are proposed, and the spatial evacuation congestion situation of each scheme is evaluated. These results confirm that in digital commercial building simulation design, the visibility loop rate of the strip path model is as high as 71.25%, which is 8.93% and 11.35% higher than that of the circular path and radiation path, respectively. Meanwhile, the reachability loop back rate of this model is as high as 76.39%. In addition, when the horizontal spacing is 2.5 m, the time for the group to complete evacuation is the shortest, only 180 seconds. And its evacuation rate reached a maximum of 0.4. When the horizontal spacing increases to 4.5 meters, the evacuation time and efficiency are close to the barrier free situation, and obstacles have little effect on reducing congestion. The adoption of the proposed method can help designers develop reasonable evacuation strategies more efficiently and safely, providing strong technical support for the field of architectural design.

    查看更多>>摘要：This research has established an energy consumption prediction model based on the Monte Carlo method to resolve the energy-saving transformation problem. First, simplify the building to construct the proposed model. Second, through the principle of building energy balance and Monte Carlo method, the cooling and heat demand model of regional buildings and the energy consumption prediction model of regional buildings are built. Finally, the energy consumption simulation and energy consumption prediction of the regional building complex after energy-saving renovation are carried out. The experiment shows that the building energy consumption in July and August was relatively high, reaching 2.36E+14 and 2.4E+14, respectively. The energy consumption in April and November was relatively low, reaching 1.2E+14 and 1.4E+14, respectively. The highest prediction error was in November, reaching 12%. The lowest prediction error was in January and February, only about 2%. The error of monthly energy consumption predicted by Monte Carlo method is less than 12%, the Root-mean-square deviation is 5%, and the error between predicted and actual annual total energy consumption is only about 2%. By comparing the predicted energy consumption after energy-saving renovation with before, the energy-saving rate reached about 20%. The research results indicate that the proposed Monte Carlo based predictive stochastic model exhibits good predictive performance in building energy-saving renovation, providing theoretical guidance and reference for feasibility studies, planning, prediction, decision-making, and optimization of building energy-saving renovation.

    57-70页
    查看更多>>摘要：With the prefabricated buildings developing, traditional architectural design methods can no longer meet the requirements of efficient, green, and sustainable development. In view of this, based on the analysis of the framework structure of the cyclical parthenogenesis algorithm, the study introduced chaotic optimization algorithm for improvement. And the improved new algorithm was applied to multi-objective problems in the optimization design of prefabricated building structures. Finally, a novel structural design optimization model was proposed. These experiments confirmed that the improved algorithm had the least 160 iterations and 17 optimal solutions, which was an increase of 15 compared to traditional aphid algorithms. Two function solutions of this new structural design optimization model were both between -0.5 and 0.5, with relatively smaller values. In addition, this model could effectively optimize and transform physical buildings, increasing their structural stability by 2.43%, increasing their structural quality coefficient by 4.49%, reducing vibration cycles by 0.06%, and reducing inter story displacement angles by 0.04%. In summary, the improved cyclical parthenogenesis algorithm has good performance in solving multi-objective problems in prefabricated structures, and can quickly and accurately find the global optimal solution. This study aims to provide guidance for the prefabricated building structure design.

    查看更多>>摘要：In order to improve the application of BIM technology in reinforced concrete structure design. Methods: This paper takes the housing project in District A of Guangzhou as the research object, and uses BIM technology to design the precast part of the reinforced concrete structure in the C household, including the deepening design of the reinforced concrete structure, production management of the precast components, tracking, address data modeling, hoisting and deployment, etc., which penetrates into all aspects of the design of the reinforced concrete structure. It was found that after the application of BIM technology, the construction period was reduced from the originally established 13 days per floor to 7 days per floor, and the on-site construction errors were reduced, the construction efficiency and construction quality were improved, and the project was successfully completed. It can be seen that the application of BIM technology in the design of reinforced concrete structures in urban buildings can shorten the construction period and ensure the construction quality at the same time. It is a favorable means to promote the development of urban construction industry and should be actively promoted.

    Application of the Rayleigh quotient method in the analysis of stability of straight elastic bars

    Radosiaw CzubackiTomasz Lewinski
    85-98页
    查看更多>>摘要：The paper deals with stability problems of straight elastic bars made of a homogenous isotropic material. The approach concerns both the bars of compact cross-sections and of thin-walled cross-sections, the transverse distortions being neglected. The stability analysis method developed for thin-walled bars in the paper: L. Zhang and G.S. Tong, "Flexural-torsional buckling of thin-walled beam members based on shell buckling theory", Thin-Walled Structures, vol. 42 (2004), pp. 1665-1687 is here extended to the bars whose deformations obey the assumptions of the Vlasov-like theory. The approach proposed makes it possible to assess the values of critical loads causing: axial tbrces, bending moments, transverse forces and torques, possibly simultaneously. The main task is to perform maximization of the relevant Rayleigh quotient; its form is given for all rational shapes of the bar's cross section. The paper shows how to assess critical axial buckling loads and lateral buckling loads of straight elastic bars made of a homogenous isotropic material.

    查看更多>>摘要：Effective engineering design of structures requires a thorough understanding of the groundwater conditions of the substrate. In some situations, a three-dimensional survey is necessary. Landslides are examples of such cases. They are complex phenomena, and the main factors significantly influencing their behaviour over time are changes in slope geometry, inclination and water conditions. The article discusses the reconnaissance of the substrate structure in an area threatened by mass movements along a modernized section of a railway line. The analysed area is located in the marginal zone of the North Polish glacial moraine. The geological structure of the substrate consists of: glacial tills, glaciofluvial sands, lacustrine clays, and organic soils found in periodically waterlogged areas and depressions in the terrain. Colluvial deposits, mainly consisting of clayey formations, occur on the slope of the escarpment. Surface geomorphology was interpreted using LIDAR data and field observations. Two-dimensional and three-dimensional electrical resistivity tomography (ERT) was used to obtain a detailed subsurface image, which was verified by borehole drilling and laboratory analysis of soil samples for physical properties, including grain size distribution and plasticity, as well as mechanical properties of soils. This research enabled the creation of a three-dimensional substrate model, showing the spatial distribution of colluvium and areas at risk of active landslides. The results indicate that an integrated approach, combining geophysical imaging and geotechnical reconnaissance, allows for a detailed understanding of the structure and lithology of landslide areas.

    113-134页
    查看更多>>摘要：This article explores the dynamic interplay between the business cycle and the housing market in Poland from 2007 to 2022. It examines the complex relationship between economic cycles and the residential property sector, focusing on the impact of government intervention and market fluctuations. The research shows that the housing market is highly sensitive to external factors. It highlights the central role of the National Bank of Poland (NBP) in shaping the housing market through changes in interest rates and credit availability. The COVID-19 pandemic temporarily disrupted developer activity and housing demand, highlighting the vulnerability of the market to unexpected shocks. In addition to observations, this study calls for a critical analysis of housing policies, identifying potential shortcomings and ottering recommendations for improvement. It underlines that economic crises are an inherent part of housing market cycles, promoting market cleansing and healthy competition. Finally, this research emphasises that the housing market is intertwined with broader economic trends. It highlights the need for central banks to strike a balance between managing inflation and supporting economic growth. This study contributes to a deeper understanding of the relationship between the housing market and the business cycle, providing valuable insights for policymaking and investment decisions.

    Risk assessment for underground utility damage due to spatial data quality

    Marek SlusarskiAnna Przewiezlikowska
    135-148页
    查看更多>>摘要：Spatial data are used in a variety of projects. Their quality directly contributes to the project's success. One of the risk sources for underground utility damage in construction works is the quality of spatial data. The article presents the results of research on a method for estimating underground utility damage risk. It consists in calculating the risk (both qualitative and quantitative risk) from specific risk factors and impact weights. The primary risk factors are incomplete spatial datasets and horizontal and vertical position accuracy of objects in the database. The calculated risk value is within 7.0 to 34.2 points. This means that the minimum risk of damage to underground utilities during construction works is 7.0 points and the maximum risk of 34.2 points is nearly five times higher. We also developed a risk map of underground utility damage. It is a thematic map with qualitative project risk. The proposed map is a 2D and 3D cartographic document that represents the actual risk of damage to underground utilities due to spatial data quality.
