NONLINEAR ANALYSIS AND STUDY ON ALLOWABLE VALUE FOR SEISMIC BEHAVIOR OF HIGH-STRENGTH CONCRETE SHEAR WALLS

Based on the seismic experiments of 4 high-strength concrete shear walls(HSCW) under cyclic loading, the nonlinear analysis was performed to simulate the complete loading and mechanical behavior by using the finite element software ABAQUS. The nonlinear characteristic of material, including a set of element models and damage constitutive relation of tensile and compress, was taken into account in the models. The reliability of the finite element model was verified by the comparison between analysis results and experimental results. Through the proposed numerical model, in the consideration of the effect of the axial load ratio , stirrup ratio, concrete strength and ratio of reinforcement, the allowable value of parameters and its range are suggested.
