NONLINEAR FINITE ELEMENTS ANALYSIS ON SEISMIC PERFORMANCE OF FRAME JOINTS STRENGTHENED BY SELF-COMPACTING CONCRETE UNDER SECONDARY LOAD

摘要：

　　Based on the experimental study of 4 self-compacting concrete frame joints strengthened, Using the finite element software ABAQUS to establish the finite element model of self-compacting concrete frame joints strengthened , Considering the material nonlinear and crushing of concrete material, simulation results are consistent with the experiment results well.The effect of limit capacity of the joints was studied by analyzing the initial force, The results indicated that initial force has some influence on limit capacity of the joints, The consolidation design should be considered.
