多层钢框架结构强度折减系数研究的中期报告 摘要： 本研究旨在探究多层钢框架结构在不同环境条件下的强度折减系数，为钢结构工程设计提供技术支持和参考。通过对多层钢框架结构的设计、构造方案和环境条件进行系统分析，采用有限元分析方法对多层钢框架结构在风、地震等条件下的强度进行仿真计算，计算并分析不同条件下的强度折减系数。初步结果表明，多层钢框架结构在地震条件下的强度折减系数较大，而在风等环境条件下的强度折减系数相对较小。未来研究将进一步优化模型和算法，深入探讨多层钢框架结构在不同环境条件下的强度变化规律。 关键词：多层钢框架结构；强度折减系数；有限元分析 Abstract: The aim of this research is to explore the strength reduction factor of multi-storey steel frame structures under different environmental conditions, which provides technical support and reference for steel structure engineering design. By analyzing the design, construction scheme and environmental conditions of multi-storey steel frame structures, finite element analysis method is adopted to simulate the strength of multi-storey steel frame structures under wind, earthquake and other conditions, and to calculate and analyze the strength reduction factor under different conditions. The preliminary results show that the strength reduction factor of multi-storey steel frame structures is relatively large under earthquake conditions, while the strength reduction factor under wind and other environmental conditions is relatively small. Future research will further optimize models and algorithms and explore the law of strength changes of multi-storey steel frame structures under different environmental conditions. Keywords: multi-storey steel frame structure；strength reduction factor；finite element analysis.
