地震激励将诱引建筑结构损伤,且损伤会由于荷载循环次数的增加而不断累积。在分析总结国内外关于楼层地震损伤模型研究成果的基础上,得出结构损伤从构件维度上考虑比从整体结构维度上考虑更能合理反映损伤演化规律。采用“预损法”并利用有限元软件ABAQUS模拟框架结构在构件各主要设计参数(如楼板作用、轴压比)变化时所引起的损伤,揭示各类构件损伤对楼层损伤的影响规律,建立往复荷载作用下钢筋混凝土框架结构楼层损伤模型。
Earthquake incentives will induce damage to the building structure, and damage will continue to accumulate due to the increase in the number of load cycles. On the basis of analyzing and summarizing the research results of earthquake damage models at home and abroad, it is concluded that structural damage can reasonably reflect the damage evolution law from the aspect of component dimensions rather than the overall structural dimension. Using “pre-loss method” and using finite element software ABAQUS to simulate the structure of the structure of the main components of the design parameters (such as floor effect, axial compression ratio) caused by changes in damage, revealing the various types of damage to the floor of the law of damage , Establish the damage model of reinforced concrete frame structure under reciprocating loads.
