Experimental Study And FEM Analysis On Pseudo-static Test Of I-Shaped Section Superimposed Slab Shear Walls

In recent years, the urbanization process is more and more speedy in our country, and the resulting housing problem of most urbanization population need combine with industrial production to resolve. The superimposed slab shear wall structural system can be industrial production, meet the requirement of green, environmental protection and sustainable development, and possessed several advantages, such as speedy construction, reduction of the form work, low pollution to the environment and good quality control. Because this structure form were introduced from Germany, it was necessary to carry on adaptive research relate to field environment in our country.Under this background, the study to the superimposed slab shear walls had vital practical significance. This paper carried out the related research based on the national youth natural science fund projects (50908071):(1)Based on the comparative experimental studies on two Ⅰ-Shaped Section superimposed slab shear walls under low cyclic loading, the structural failure feature, deformation capacity, ductility, stiffness degradation, hysteresis behavior, and energy dissipation capacity were analyzed systematically.(2)In order to appraise and judge the damage of the structure or component after earthquake, the seismic damage model based on stiffness and the seismic damage model based on displacement and energy for these shear walls were analyzed and compared. The calculating results of the two different seismic damage indexes and the experimental phenomenon were in good agreement. The seismic damage model based on stiffness computed more easily and could be used first.(3)At last, based on the test, nonlinear finite element analysis of the shear walls was carried out by ABAQUS program. The finite element computing results agreed with the test well.
