Vulnerability Assessment of Truss Structure Based on Strain Energy and Damage Scenarios

Abstract:

The method of structural vulnerability assessment presented in this paper is closely in accordance with the definition based on two aspects, strain energy of structure and damage demand of members. The search process of damage scenarios was carried out by an example of truss structure, and the results of analyses included importance factor of members, damage scenarios with the minimum number of killed members, and local damage occurred in advance. The influence of loading on member importance factor and vulnerability index was discussed and it showed that though with the agreement of general trend, the rank of importance factor or VI index under a specified scenario varied greatly. The analysis could be utilized as the proof of measures to enhance structural capacity to meet the extreme event.
