BASE ON DEFORMATION OF NONLINEAR FINITE ELEMENT ANALYSIS ON HIGH PERFORMANCE CONCRETE STRUCTURAL WALLS
Base on the experiment on high performance reinforced concrete (HPC) structural walls, nonlinear finite element analysis was performed to simulate the complete process of the loading and concrete crack of HPC structural walls in the platform of ABAQUS. The nonlinear of material are taken into account in the models. The reliability of the finite element model was verified through the comparison of the analysis results and the experimental results. Based on the proposed model, the parametric analysis is carried out to study the effect of axial load ratio, aspect ratio, stirrup characteristic value, and reinforcement ratio on the seismic behavior of HPC walls. It is concluded that with the increase of the axial load ratio, the bearing capacity of HPC structural walls increase, and the deformation capability decreases obviously. The bearing capability of the structural walls is improved by increasing the reinforcement ratio. With the increase of the stirrup characteristic value, the deformation capability of the structural walls improves. The allowable axial load ratios are proposed when the target ultimate drift ratios are 1/80, 1/100, 1/120, respectively.
