Abstract

A simulation method to detect and locate damage in frame structures by defining a damage index is proposed. Structural members are Timoshenko beam type. The method defines a damage index which is the reduction percentage of H2 norm of the structure at certain locations in both healthy and damaged states. Structure modeling is done by finite element method.
