型钢混凝土剪力墙边框柱-腹板组合分析模型研究
Column-web combined model for steel-reinforced concrete shear wall
摘要
Abstract
The deficiencies and related reasons of existing finite element analysis (FEA) model for steel-reinforced concrete (SRC) shear wall was investigated.According to the stress characteristics of SRC shear wall,the geometrical model,material constitutive relation,mesh generation and the limit state criteria were researched.Based on the rotating angle softened truss model(RA-STM) which can reflect mechanical behavior of shear reinforced concrete web,a material user subroutine was developed based on the ABAQUS,and a column-web combined model was developed to simulate the SRC shear wall.Ten SRC shear walls with shear-span ratios ranging from 0.56 to 2.7,and axial compression ratios ranging from 0.1 to 0.342 are compared to verify the column-web combined model.The simulation results for the peak load and ultimate displacement agree well with the test results.The whole load-displacement curve and the failure mode of the SRC shear wall can be accurately simulated.关键词
