The finite element model of full size RC-L column is established by using finite element analysis software ANSYS.The element types,control parameters and material models of concrete,steel bar and angle are set respectively and the grids are divided finely.Based on the analysis of FEM simulation,the stress and the corresponding load-displacement curves of concrete,steel skeleton and the external angle of RC-L-shaped column model are obtained.Under the same boundary conditions and loading,the model reinforced by wet-enclosing steel takes more load steps and produces a smaller sub-shift before the damage when compared with the model without reinforcement.Comparing with the analysis results,it can be seen that it has a good performance to reinforce RC column with special shape by wet-enclosing steel reinforcement method.
