Failure Modes-Based Searching and Optimizing of Steel Reinforced Concrete Frame Structures

Abstract

Taking the optimization of steel reinforced concrete frame structure as background, the searching and optimizing of structural were taken as optimization objectives by introducing failure modes. Incremental dynamic analysis (IDA) was used to search the seismic wave, which had important significance of the structure, thus, the failure modes under the seismic waves could be obtained. And three optimization methods were proposed. Finally, an example was analyzed to verify the rationality of the proposed optimization thought and method.
