Ductility performance of reinforced concrete frame structure with specially shaped columns

Expounded research techniques and influencing factors of reinforced concrete´s ductility are studied in detailed. The constitutive relationship is selected between concrete and reinforce during simulation and analysis, a Three-ply reinforced concrete frame structure with specially shaped columns is simulated by finite elements program of ANSYS. The results of simulated approached to experimental dates. Which mean that use ANSYS program simulated ductility performance of reinforced concrete frame structure with specially shaped columns under reversed cyclic load is feasible. The simulation reflected the ductility of reinforced concrete frame structure, in which from load-on till destruction, is perfectly. Compared to other parts, bearing is the weak point of the framework, strengthening the bearing parts is the key to improve the bearing capacity of the whole project. In order to meet the engineering requirements, increasing the bearing cross-section dimensions, the reinforcement of the bearings and other measures can strengthen the shear capacity of the bearings.
