【Abstract】 The simplified formula of the maximum displacement for the long-term elastoplastic system under earthquake is introduced.Based on the quasi-static experimental study of the self-centering post-tensioned precast frame(simplified as PTED) connections,the effect of the strength reduction factor and hysteretic energy coefficient on structural displacement of PTED structure is discussed.On the basis of opensees and the simplified formula,the calculation process of the maximum displacement of the PTED frame structure under earthquake is given by the numerical example,and the dynamic analysis is utilized to verify the accuracy of the formula.更多还原
