| Abstract: | 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 ... |
