等效斜压杆理论是模拟混凝土框架填充墙的常用方法之一.为探索该理论在结构抗震动力时程分析模拟中的应用,基于有限元软件ABAQUS,针对某一多层框架砌体填充墙结构案例,建立梁杆单元模型.模型中运用改进后的等效斜压杆宽度计算公式,来定义交叉杆的截面属性,并通过子程序建立材料的非线性本构关系.通过该模型系统分析了其在地震作用下的动力时程响应,并进行了比较研究.计算结果表明,使用等效斜压杆理论对实际框架填充墙进行模拟是可靠的,可以为工程设计提供参考依据.
Equivalent bar technology is one of the most common methods to simulate the infill walls filled with concrete frame.In order to explore the application of the theory in the seismic simulation of structural seismic power, based on finite element software ABAQUS, Structure case, the beam element model is established.In the model, the improved cross-bar equivalent width calculation formula is used to define the cross-section properties of the crossbar, and the nonlinear constitutive relation of the material is established through the subroutine program. Through the systematic analysis of the model The dynamic response of the system under earthquake action is studied and compared.The results show that it is reliable to simulate the actual infill wall with the equivalent inclined bar theory and can provide a reference for engineering design.
