First Claim
1. A computerized method for resilient design comprising:
- a) accepting user input to establish functional, geometric and load criteria for a structure and its members that meets resiliency design criteria;
b) generating a structure system design including a plurality of members, wherein the design satisfies the resiliency design criteria;
c) evaluating at least one of stability of the structural system design, damage effects within the structural system design and propagation of damage effects within the structural system design, and load redistribution under a plurality of simulated damage events, wherein the integrity of particular members or components of members are compromised in the simulated damage events and evaluating structural stability and safety criteria after the damage events;
d) reconfiguring the structure system design, its geometry, and at least one of member layout and composition to improve its structural stability, residual load resistance, and structural reaction in response to the damage events;
e) iteratively repeating steps (b) through (d) using the reconfigured structure system design; and
f) outputting the structure system design to the user after or during multiple iterations of steps (b) through (d) for construction of a structure in accord with the structure system design.

Abstract
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.
