【摘要】 目前,国内外许多学者在RC框架结构砌体填充墙抗震性能方面做了大量研究,包括有限元建模分析以及实体实验,并得到了一些成果。对于填充墙平面内破坏全过程已有了较为清晰的认知,但对于其各破坏阶段的划分以及具体的划分标准仍有待进一步厘清。本文基于填充墙抗震性能的实验数据,根据弹塑性表现,划分出四个破坏阶段,并以层间位移角为弹塑性限值,量化划分指标。从三个不同角度计算层间位移角限值,与实验数据结合,通过区域覆盖率比较得出合适的方法。更多还原

【Abstract】 At present,many scholars have done a lot of research and obtained some achievements on masonry infilled walls with RC frame in terms of seismic performance domestically and internationally,including the modeling of finite element analysis and physical experiment.There is a clear understanding of the whole process of failure in the plane of the filled wall,but the division of each failure stage and the specific dividing criteria still need to be further clarified.Based on the experimental data of the seismic performance of the filled wall,four failure stages are divided according to the elastoplastic performance.The story drift is taken as the limit value of elastic-plastic to quantify the index.Calculate the limits of story drift from three different angles,and the appropriate method is obtained by comparing the ratio of area coverage with the experimental data.更多还原
