The clamping force between the beam and the column provides vertical shear force transfer at the interface between the beam and the column. Under seismic loading , nonlinear behavior occurs at the interface between the beam and the column. The remainder of the beam and the column remain elastic. So the frame behavior is controlled by the unbonded post-tensioned precast concrete beam-column connection behavior. The object of this paper is to investigate the aseismic capacity of the unbonded post-tensioned precast concrete frames by Pseudo-elastic method. Firstly, the moment-curvature curve of member section have been established. Secondly, the structure will be analyzed linearly by adopting SAP2000+ software, the member in linear forces can be figured firstly. The structure nonlinear performance will be analyzed by using Pseudo-elastic method, which will transfer the member energy which exceeding the elastic range into plastic energy. Then the nonlinear response of the frame can be finally carried out, and the ultimate lateral capacity, ultimate drift, ductility and collapsed ground acceleration for frame can be determined from which the structure aseismic capacity can be assessed.
