Resilient Design Method for Improved Safety and Security of Structural Systems

摘要

In a resilient design method, input from a user (and possibly from a knowledge base and prototype designs) is accepted to establish functional, geometric and load criteria for a multi-hazard resilient design structure. A structure system design is then generated that satisfies those functional, geometric and load criteria. Various damage events are then simulated, wherein the load-bearing capacity (integrity) of members in the structure are compromised, and the redistribution of loads across members in the damaged structure and the structure stability is evaluated. The structure design is then reconfigured based on that evaluation to improve its structural stability and residual strength. These steps are iteratively repeated to incrementally improve the structural stability and residual strength of the structure across a variety of potential damage events; and a resilient structure can then be built in accord with the resulting design.
