变刚度框剪结构位移分析及剪力墙刚度优化

Displacement Analysis for Frame Structure with Variable Stiffness and Shear Stiffness Optimization

通过对变刚度框剪结构层单元模型分析,推导出整体刚度方程,并考虑多振型因素的影响,提出了确定地震区沿高变刚度框剪结构剪力墙最优数量的简化计算方法,用MATLAB编制了相关程序,可便捷地算出剪力墙的最优刚度及各种地震作用情况下的位移,为结构初步设计带来便利。

Based on the element model analysis for the frame and shear structure with variable stiffness,the overall stiffness equation is derived,and taking into account the impact of multi-modal factor,the simplified calculation methods are proposed to determine the optimal number along the shear walls of the frame structure with variable stiffness in the earthquake zone.At the same time,the relative procedures are developed by MATLAB,by which the optimal stiffness of shear walls and displalement in different cases of earthquake could be calculated easily,and the convenience could be brought to the preliminary design for strutures.
