Effects of Changing Stiffness of Shear Wall on Internal Force of Columns in the Structure

The relationship between the floor shear of rectangular-column frame and the eigenvalue of stiffness of frame-shear wall structure is given based on the basic differential equation of the coordination of frame-shear wall structure with rectangular columns.The effect of the variation of the bending stiffness of shear wall on internal force of rectangular columns is analyzed in highrise building of RC frame-shear wall structure,and an example shows the variation of internal force of rectangular columns in adjusting quantity of shear wall and optimizing the lateral stiffness of shear wall.
