On the post-earthquake damage detection of structures
Keywords:
damage, earthquake, dissipated energy, hysteresisAbstract
The paper introduces an alternative method for evaluation the post-earthquake damage in the multidegree of freedom structures with viscous and hysteretic behavior. Assuming damage as a scalar variable is very simplistic. However, this simplification helps us to understand the damage as the failing which impairs functional and working conditions of engineering structures. The damage is computed from simulated data and the characteristics of the structures. The role of the strength and stiffness degradations in the damage evaluation is investigated, via extended Bouc-Wen model. The transition to damage as a vector variable is in progress.
