Fine-grained Applications of BIM Technology in the Whole Life Cycle of Green Buildings Based on Case Analysis

Qingyuan Hu — 2026-01-28

Against the backdrop of the global decline in environmental resources, in response to the national call for environmental protection, green buildings have gradually become the core of the construction industry’s development. As a digital technology that has been continuously innovated in recent years, Building Information Modeling (BIM) technology has played a significant role in many green building projects. This paper, based on the application of Building Information Modeling technology and the requirements of green buildings, combines specific cases to analyze the application of Building Information Modeling technology in each stage of the green building’s life cycle and the changes it has brought. The results show that compared with traditional construction methods, Building Information Modeling technology, with its advantages of greater refinement, visualization, and data-driven approach, has had a significant impact on reducing resource and energy consumption in building construction while meeting industry standards and human needs.

As one of the core technologies for force transmission and deformation coordination in prefabricated building structures, the performance of connection nodes directly determines the overall safety, stability, and durability of the structure. With the current changes in prefabricated building structures, the performance of traditional connection nodes has gradually exposed many problems. Based on this, this paper analyzes the performance and significance of connection nodes in prefabricated building structures and explores their optimization paths, aiming to provide theoretical support for the efficient construction and high-quality development of prefabricated buildings.

Study on Static Three-Component Aerodynamic Force Coefficients of a Streamlined Box Girder Based on CFD

Shijie Guan — 2026-01-28

A systematic investigation on the static three-component aerodynamic force coefficients of a streamlined box girder cross-section is conducted using the Computational Fluid Dynamics (CFD) approach. The Reynolds-Averaged Navier–Stokes (RANS) equations coupled with an appropriate turbulence model are employed to establish numerical simulation models of the bridge girder under various angles of attack. The flow field structures and aerodynamic characteristics around the main girder are simulated and analyzed in detail. By comparing the variations of lift, drag, and moment responses under different angles of attack, the characteristic curves of the three-component force coefficients are obtained. Furthermore, the locations of key flow separation points, the evolution of wake vortex structures, and their influences on aerodynamic force variations are examined to elucidate the underlying flow mechanisms governing the changes in aerodynamic coefficients. The results provide theoretical insights and technical support for wind-resistant design, aerodynamic optimization of streamlined box girders, and the selection of wind tunnel test parameters.

Research Progress and Prospects on the Performance of Recycled Aggregate Concrete under High Temperature

Xiaoqing Hu — 2026-01-28

This paper systematically reviews domestic and international research literature on the performance evolution of recycled aggregate concrete under high-temperature conditions in recent years. It summarizes the influence patterns of factors such as temperature, aggregate replacement rate, and fiber admixtures on the high-temperature performance of recycled aggregate concrete from the perspectives of macroscopic mechanical properties, microscopic degradation mechanisms, and performance improvement techniques. The analysis indicates that the interfacial transition zone is a weak link in the high-temperature damage of recycled aggregate concrete; its high-temperature resistance can be effectively enhanced through methods such as fiber reinforcement and alkali-activated cementitious systems.

Research and Application of Comprehensive Protection Technology for High-Fill Embankment Slope: A Case Study of an Urban Road in Hunan Province

Liang Bao — 2026-01-28

This paper takes the high-slope project of a newly built urban road in Hunan Province as the research object and systematically analyzes its geological conditions, hydrological characteristics, and slope stability issues. In response to the characteristics of high fill slope height (9–17.3 m) and high safety level (Level I), a comprehensive treatment plan was proposed, incorporating “anchored pile-sheet retaining walls, slope ratio method, interception and drainage, and greening protection”. The paper elaborates on the design of the support structure, construction techniques, quality control, and deformation monitoring, with a particular focus on discussing the collaborative working mechanism between prestressed anchor cables and anti-slide piles, the timing control of layered filling and anchor cable tensioning, as well as the information-based construction and emergency response mechanisms. Research indicates that this plan demonstrates good applicability and safety under complex geological conditions and limited slope relaxation, providing a technical reference for similar high-slope projects.

Shenghui Yang — 2026-01-30

To address issues such as data fragmentation, low visualization, and delayed early warning in traditional bridge construction monitoring, an intelligent monitoring system for bridge construction that integrates BIM (Building Information Modeling) and IoT (Internet of Things) technologies is proposed. Firstly, the core application requirements and technical challenges of BIM and IoT technologies in the field of bridge engineering are outlined. Secondly, a four-tier architecture system consisting of the “perception layer–transmission layer–data layer–application layer” was constructed, with a focus on explaining the functional modules, hardware selection, and software integration solutions at each level to achieve real-time collection, dynamic modeling, and intelligent analysis of key parameters such as structural stress, settlement, temperature, and equipment operational status during the construction process. Finally, based on an actual bridge engineering project, system application verification is conducted. By comparing the application effects of traditional monitoring methods with those of the intelligent monitoring system, the feasibility and superiority of the system in enhancing construction monitoring accuracy, efficiency, and safety management capabilities are validated.
