Abstract

Abstract

To investigate the influence of ground motion duration on the seismic response of self-centering prestressed concrete (SCPC) frames characterized by semi-rigidity, a friction based SCPC frame located in the area with a seismic fortification intensity of eight degree is selected as the analytical case, and its numerical model has been built. Two sets of artificial ground motions with 20 s and 60 s duration, generated based on code response spectrum, were used as the excitation for structures. The nonlinear dynamic analyses were performed on the SCPC frame under moderate and major earthquakes through finite element model of OpenSees. Results show that the ground motion duration has minor influence on the seismic response of structures under moderate earthquakes and the structures can be used immediately. Under major earthquakes, the structure can achieve the performance objective of repairable under the earthquake with short duration, while long ground motion duration may lead to larger displacement and residual deformation of lower floors, and aggravate the damage of beam and column, the objective of repairable under major earthquake is not achieved easily.
