An Evaluation Method of Structural Redundancy under Earthquake Action

Abstract:

Redundancy is an important component of structural robustness. A method is proposed based on the response sensitivity for assessment of the redundancy of structure under earthquake. Redundancy analysis is carried out for a single-layer reticulated dome subjected to earthquake condition. The result shows that the redundancy values are able to reveal the weak links in the structure. Members with a small redundancy are identified as structural weaknesses that are easily damaged under loads, and their failure may cause catastrophic consequences to the structure. Therefore, the members with small redundancies must be treated as key components of the structures.
