The study not only involves the influence of tire lateral stiffness and tire inflated pressure on aircraft nose wheel shimmy on the basis of the model, but also finds that tire lateral stiffness and tire inflated pressure are one key tire parameter which influences shimmy.

The tire model is then applied to the frontal offset impact simulation of complete vehicle to analyze the effect of tire stiffness on the consequences of impact.

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.
