[Abstract]:Actively researching and developing new green environmental protection building materials and popularizing green building wall materials are the development trend of our country's housing industry. Green environmental protection building material gypsum wall board has many advantages in the building structure. It was originally designed and produced by Australia. In recent years, the related technology has been introduced and developed in our country. Tianjin Development Zone Fulin Development Co., Ltd. has developed and produced an external insulation gypsum / polystyrene composite board with waterproof glass fiber plasterboard and polystyrene board insulation material, which is made into a wall board finished product in the factory and cut into a wall board according to the design requirements to meet the requirements. The gypsum board with cavity is used as the permanent non-detachable formwork on both sides of the cast-in-situ reinforced concrete wall to form a new type of composite concrete-gypsum wallboard with external thermal insulation. This type of wall is a new type of environmental protection building wall, which can take the place of the traditional load-bearing shear wall and has a great development prospect. At present, the research on the structure performance is still in the initial stage of research and development. In order to find out the seismic performance of the new composite concrete-gypsum wallboard, The experimental study of low cycle repeated seismic performance and finite element numerical analysis are of great significance in engineering. In this paper, the low cycle repeated test and numerical simulation are carried out on the basis of the construction of two three-story residential test buildings with a new type of composite concrete and gypsum wallboard in Fulin Development Company of Tianjin Development Zone. The research results and innovation of this experiment are mainly shown in the following aspects: 1. Three new composite concrete-gypsum wall L joint specimens were designed, and the low cycle repeated load tests under fixed axial compression were carried out, and the failure process, shape and stress characteristics of L shaped specimens under horizontal repeated load were found out. Deformability, etc. Based on the experimental data, the cracking load, yield displacement and ultimate load of the L-shaped composite concrete-gypsum wall slab under fixed axial compression and low cycle cyclic loading are analyzed and studied. The ultimate displacement and other mechanical properties, and through the ductility, stiffness degradation, hysteretic performance and energy dissipation performance of the L-shaped specimens, the seismic behavior of the joints is studied, and it is concluded that the L-shaped joints are relatively difficult to destroy under this load. Has a certain safety. The nonlinear finite element analysis of a new type of composite concrete-gypsum board wall panel L shape specimen is carried out by using the large and universal finite element analysis software ABAQUS, and the results are compared with the low cycle repeated test results, and the results are in good agreement with each other. It provides a reference for computer simulation of other specifications of new composite concrete-gypsum wall panel low-cycle repeated tests.
