As for wall segment with no holes, formulas of equivalent lateral stiffness of storey.

In order to overcome the harmful effects caused by anti-roll torsion bar,the technical strategy which can be able to promote what is beneficial and get rid of what is harmful,was proposed by the concept of anti-roll equivalent stiffness.

Tire cornering characteristics can be accurately reflected by effective cornering stiffness which is an important parameter in research of vehicle handling and stability.

Based on finite element analysis of high-rise buildings whose transfer stories are set at the first story and act as open floor,this paper discusses three types lateral stiffness control parameters of transfer story: story lateral stiffness ratio,equivalent shear stiffness ratio and equivalent lateral stiffness ratio.

Control analysis on the ratio of the first story and second story lateral stiffness for masonry building with frame structure at the first story;

If the stiffness of the floor stab can be considered as rigid enough,the lateral stiffness of the correlative columns could be calculated directly using conventional D-value method.

It is complex to calculate accurately the lateral stiffness of shear walls of transitional story of masonry building with frame-wall structure at bottom story.
