Abstract
In order to study what amount of lateral force and varied axial force are carried by the wall frame in reinforce concrete buildings with multi-story shear wall and how the rigidity at the bottom of the wall frame affect the amount of them, a pseudo-dynamic test with 2-span-1-bay-6-story reinforced concrete structure with a multi-story shear wall was conducted with the parameter of the rigidity at the bottom of the wall frame. In this paper, the test results were discussed with the numerically calculated strengths in terms of the varied axial force borne by the wall frame. They were found that both column in open frame and side column of shear wall bear varied compression force proportional to their geometrically supporting area. The varied tensile force borne by the side column of shear wall was determined by the flexural strength of transverse ground beams for the rocking specimen, and by the tensile yielding strength of the side column of the shear wall for the rigid specimen. The remaining varied tensile force was borne by the open frames.
