Abstract

Abstract:

In order to study the seismic performance of two different forms of structures， i.e. "functional integration" and "functional separation" in the Reinforce Concrete （RC） frame-seismic wall dual structure system， quasi-static tests of two 1/3 scale frame-seismic wall specimens with two single-story and two-bay were carried out. The damage development， hysteretic behavior， stiffness degradation， energy dissipation capacity， ductility and other seismic behaviors of the seismic wall were investigated as the wall mainly bears the lateral resistance but bears a small part of the vertical load， and as the wall bears both the lateral resistance and the vertical load. The performance of the specimens was also studied by ABAQUS finite element software simulation， and the results are consistent with the test results．The results of this study show that the structure has better ductility， energy dissipation capacity and damage development process when the load-bearing function and the anti-lateral function of the seismic wall are separated.
