Abstract
In order to investigate the seismic performance of a new hybrid structural system which is consisted of self-centering open frames and energy dissipation walls, the dynamic response analysis of the structural model has been carried out. The analytical model of the energy dissipation wall was already verified by the comparisons between the test results of the three-story wall specimens and its elasto-plastic analysis. In this paper, the analytical model of the self-centering frame is discussed on the bases of our previous experimental work. The simple calculating method for the horizontal load carrying capacities of the frames is developed. Also, the analytical model based on the stress-strain relation of the material is developed to simulate the load-deformation relations of the tests. The analytical results trace the characteristic behavior of the test results which are stiffness, maximum strength and residual deformation. The both of the analytical models of wall and frame are combined and used for the dynamic response analysis of the hybrid structural system. The analytical models of the six-story and three-story buildings with the hybrid structural system are made to investigate the structural characteristics. The analytical results show that the proposed hybrid structure possesses both of the high hysteretic damping effect and reduction effect of the residual deformation against the input earthquake motions.
