摘要

以某3层钢筋混凝土框架结构为分析对象，考虑不同的填充墙布置，进行多遇地震作用下的计算分析。结果表明分析模型中考虑填充墙及其不同布置时，结构的动力特性、规则性特征、以及内力分布等结构的抗震性能均受到明显影响。需要指出的是在多遇水平地震作用下，由于填充墙的约束作用，框架柱端节点弯矩远大于梁端弯矩。建议结构抗震分析时，力学模型中应增加考虑填充墙参与受力计算。

Abstract

Based on a three-story RC frame

the analysis of the structure with various layouts of infill walls under frequent earthquake was conducted. The results indicate that when the infill walls and their different layouts are incorporated into the structural model

the seismic performance

such as dynamic properties

characteristics of regularity

and internal force distributions would change significantly. It should be also mentioned that because of the constraint of infill walls

the sum of moments at column ends is much larger than that at beam ends at the frame column-beam joints. It is suggested that infill walls should be adequately considered in the mechanical models during seismic analysis.
