摘要

摘要: 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。

Abstract: The structural damage which is caused by seismic excitation is cumulated with the increment of cyclic loading times.Based on the summary and analysis of domestic and overseas research on the storey damage models, the conclusion that the law of the storey damage evolution can be reflected better in the component level than in the overall structure level is presented.With the finite element program ABAQUS, the different degrees of damage produced by the change of the main design parameters of components such as the effect of floors and the axial-compression ratio are simulated.The law of the storey damage evolution affected by the component damage is revealed.And the storey damage model of RC frame structure is finally established.
