摘要
围绕钢框架节点在循环动荷载作用下结构性能进行分析。综合讨论耗材性能、延性性能和刚度对结构变形和承载性能影响,分析塑性铰的功能和开展的条件,并给出强度破坏所依据的准则,强调方案最优化设计的重要性。利用ABAQUS软件针对钢框架在低周循环荷载下的结构性能进行数值建模分析,为建筑同行在进行相似案例设计时提供相关参考。
The structural performance of steel frame joints under cyclic dynamic load is analyzed. This paper comprehensively discusses the effects of consumable properties, ductility and stiffness on structural deformation and load-bearing performance, analyzes the function and development conditions of plastic hinges, and give the criteria for strength failure, emphasizing the importance of optimal design of the scheme. This paper uses ABAQUS software to conduct numerical modeling analysis on the structural performance of steel frames under low-cycle cyclic loads, and provide relevant references for construction colleagues when designing similar cases.
