Abstract

In this paper the main results of a study of the influence of hysteretic models on the nonlinear seismic demand of SDOF structures are presented, with a focus on energy demand useful in the evaluation of cumulative damage effects. The results have been obtained within the framework of the earthquake input energy and associated parameters which have been performed by the authors at the University of Rome “La Sapienza”. Seven hysteresis models have been used to describe the nonlinear force/deformation behaviour of the SDOFs. Four of them simulate predominantly flexural behaviour of reinforced concrete structures: EPP model, Clough’s model, Takeda’s model, pinching degrading model. The shear behaviour of reinforced concrete and masonry structures is simulated by three variants of the shear-slip model. The influence of different soil types has been carefully studied
