Abstract:
The fiber model in 3-dimensional nonlinear analysis program CANNY was used to simulate walls, and the uniaxial spring model was adopted to simulate beams. Elasto-plastic analysis of reinforced concrete coupled shear wall was carried out. Based on the comparison analysis with test result, the trilinear skeleton hysteresis model and proper material stress-strain relations were selected for simulating reinforced concrete coupled shear wall model. Through numerical calculations, the influences of design parameters, such as axial compression ratio, reinforcement ratio of steel bars for wall distribution, reinforcement ratio of longitudinal bars for beams as well as reinforcement ratios of marginal members on bearing capacity, ductility, failure shape for reinforced concrete coupled shear walls were considered. The results indicate that the axial compression ratio, reinforcement ratio of steel bars for wall distribution, reinforcements of marginal members significantly affect the mechanical behavior of reinforced concrete coupled shear walls, and reinforcement ratio of longitudinal bars for beams less affect the behavior; the analysis model is proved to be effective.
