The influence of ground motion duration (GMD) in seismic response of structures is investigated using single degree of freedom (SDOF) systems with different constitutive laws to represent structures with different levels of degradation in strength and stiffness. Two different demand measures are considered to represent maximum and cumulative response. GMD influence is studying using two specific duration scenarios to consider short and long duration, each with 20 records. The study is divided in two parts, in the first part incremental dynamical analysis (IDA) is used to evaluate the influence of GMD in the seismic response of structures with different hysteretic behaviour for both demand measures used, and different levels of ground motion intensity. In the second part, fragility curves are obtained to evaluate the influence of GMD on structural failure probability of structures with different models of hysteretic behaviour.

Abstract
The influence of ground motion duration (GMD) in seismic response of structures is investigated using single degree of freedom (SDOF) systems with different constitutive laws to represent structures with different levels of degradation in strength and stiffness. Two different demand measures are considered to represent maximum and cumulative response. GMD influence is studying using two specific duration scenarios to consider short and long duration, each with 20 records. The study is divided in two parts, in the first part incremental dynamical analysis (IDA) is used to evaluate the influence of GMD in the seismic response of structures with different hysteretic behaviour for both demand measures used, and different levels of ground motion intensity. In the second part, fragility curves are obtained to evaluate the influence of GMD on structural failure probability of structures with different models of hysteretic behaviour.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
