Topology-Based Quantitative Analysis of Structural Robustness

Robustness has been recognized as the ability of a structure to maintain stable functioning in the face of local damages. The purpose of the robustness analysis is to quantify such an overall performance and to identify the defect of the structural topology. This paper presents a methodology to quantitatively analyze the structural robustness from the topological point of view. In the proposed method, the structural failure is viewed as a transformation and feedback process between the damage input and the failure output. By using the uncertain disturbance and the topological change of the structure to respectively measure two such quantities, the transfer matrix is established not only to describe the structural topology, but also to determine the operation of the closed-loop system. By studying the related properties of the transfer matrix, the importance of each loading path, the robustness of the entire structure, as well as the most vulnerable part of the system can be found concisely.
