框架填充墙的等效弹簧斜撑模型
|
摘要
填充墙的破坏形式较为复杂,为了有效地模拟填充墙的非线性性能,在对恢复力模型研究的基础上,提出静力非线性分析方法。由于SAP2000软件中无法直接模拟填充墙的非线性性能,本文结合填充墙的破坏特征,使用LINK单元建立填充墙等效模型,通过与试验结果对比,验证了该模型的合理性。在此基础上,以某5层框架填充墙结构为算例,建立考虑填充墙和不考虑填充墙的分析模型,分别进行了模态分析和Pushover分析。分析结果表明,考虑填充墙影响的周期折减系数为0.4～0.5,填充墙对框架结构中塑性铰的出铰顺序、塑性铰的发展情况都会产生重要影响。
The damage form of the infilled wall is complex,in order to effectively simulate the nonlinear properties of the infilled wall,the method of static nonlinear analysis is proposed which is based on the research of restoring force model.The non-linear properties of infilled wall can't be directly simulated in SAP2000,according to the failure characteristics of the infilled walls,so the link unit is used to establish the equivalent model of infilled wall.Comparing the mode results with experimental results,the effectiveness of this model is verified.On the basis of this,take five-layer infilled frame structure for the example.The analysis model of considering filled-wall and not considering filled-wall are respectively established to conduct modal analysis and pushover analysis.The conclusion shows that the period reduction factor of considering the influence of infilled wall is 0.4~0.5,and the infilled wall will have important effect on the sequence and development of the plastic hinge in the frame structure.
