And in order to find out if the cables, lateral stiffness of column, stiffness of compression ring and the vertical struts are sensitive to Levy dome, the Monte Carlo method and the orthogonal design method were adopted, static and dynamic analy.

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.

Based on interaction of filling wall and frame structure,the lateral rigidityof filling wall and frame structure has been analyzed under horizontalload and the influence extent of filling wall on dynamic characteristicof frame structure.

The simplified formulas used to calculate the masonry structure lateral rigidity and internal force are presented.

This paper sums up the calculation methods and equations of lateral rigidity of brick wall and reinforced concrete wall in our country at present, relates the regulations of lateral rigidity calculation of wall with small opening.
