Experimental Research And Finite Element Analysis On Seismic Behavior Of RC Mid-rise Shear Wall

Shear wall structure is widely used in the building construction, and its seismic behavior have attracted considerable research attention. Previous research however, was mainly focuse on the seismic properties of low-rise shear wall, the research of seismic properties on mid-rise shear wall with frame columns are very far from satisfaction. In this paper, therefore, two model of shear wall structures are applied to investigate the seismic behavior through pseudo static test. The major contents are as following:Through a test of 1/15-scaled model, the shear wall of a longitudinal frame-shear wall structure main factory building of the large power plant is modeled as testing model structure, and is tested by pseudo static test. This paper mainly investigates the loading behavior, failure proceeding, strength, rigidity, deformation, ductility and energy dissipation capacity of the model structure. By modifying the level and vertical steel bars and adding bevel steel bars to the model structure, the paper compares the influencing factors of ratio of reinforcement and bevel steel bars to seismic properties, and pushes forward the methods to improve the seismic behaviors of the same kind.Meanwhile, by using delaminating combination finite element method and macro finite element analysis methods, the paper present two kinds of analysis programs. Based on the aforementioned analysis program, the failure form, distribution of plastic hinge, load-carrying capacity, displacement and ductility characteristics are investigated to reveal the failure mechanism and the failure proceeding under seismic effects. The results are in good agreement with the test results, indicating the precision of the aforementioned two programs is satisfiable to the practical engineering design. As a result, the two programs are applicable to the analysis and design of the similar structure.
