Failure-Mode Based Coupled Shear Wall Optimization Design

Failure-mode based optimization is very effective at improving the performance of structure, therefore, a new optimal approach based on failure mode with the ability to limit the cost is proposed. Three different failure modes of the coupled wall are discussed, and then the objective function is setted up according to the expected failure mode and minimum cost. Finally, an example is cited to verify the method. It is concluded that the method can supply an effective way to reduce the cost of coupled shear wall, and the expected failure mode can be obtained.
