Compare with under frame anti-shake wall structure opening the hole wall lateral rigidity algorithm;

The impact of the story with outriggers on the lateral rigidity of the structure was studied using the finite element method,and the calculation result and the executing plan were given out.

Then,based on the thermal stress and its distributed regulation of large area floor,several details,such as tempture load,lateral rigidity of vertical structure member are given.

Analysis of lateral stiffness for R C frames with special-shaped columns;

The calculation method of lateral stiffness in the condition of frame-shear wall cooperation are used,the lateral stiffness ratio between the first and second storey are calculated and the conclusion that lateral stiffness could not meet practice s need when the first and second storey were provided with the same structure and h_1/H>0.

The layout affects the lateral stiffness of the structure.

Based on comparing the results of structure systems, the paper reach the conclusion that the sandwich rubber cushion effectively control displacement response of the additional stories structure, and the displacement of each storey are significantly decreased, especially the stiffness mutation of the directly storey-adding are relieved .

With the development of multi-functional architecture, tall building structures with lateral stiffness varying in vertical direction are widely used in seismic zones.
