Abstract:
In order to study the out-of-plane mechanical behavior of assembly double-face superposed shear wall with horizontal joint, the out-of-plane static loading test and finite element parameter analysis of one full-scale specimen of double-face superposed shear wall and one cast-in-place shear wall were completed. The failure mode, load-displacement curve, stiffness degradation characteristics and the force transfer performance of the vertical connection reinforcement at the horizontal joint were compared and analyzed. The out-of-plane bending capacity and the shear bearing capacity of the horizontal joint section of the double-face superposed shear wall were proposed. The results show that the failure modes of the double-face shear wall and cast-in-situ shear wall are basically the same, both of them are out-of-plane bending failure. Compared with the cast-in-situ shear wall, the initial crack of the double-face superposed shear wall specimen appears at the bottom horizontal joint, and then the crack appears on the wall surface and develops progressively upward, showing good ductile failure characteristics. The double-face superposed shear wall specimen has higher out-of-plane bending capacity and deformation capacity, and their initial stiffness, ultimate bearing capacity and out-of-plane displacement ductility coefficient are all larger than those of cast-in-situ shear wall specimen. The simulation results of finite element calculation of double-face superposed shear wall specimen are in good agreement with the experimental results. With the increase of axial compression ratio, the out-of-plane bearing capacity of the double-face superposed shear wall increases significantly, but the ductility decreases obviously. The smaller the height to thickness ratio, the higher the out-of-plane bearing capacity of the double-face superposed shear wall, but it has little effect on ductility. The calculated results of flexural bearing capacity formula proposed are in good agreement with the test results, which can be used to guide engineering practice.
