Optimum buckling-restrained braces application to enhance seismic performance of RC frame with curtailed walls

Reinforced concrete (RC) frames are commonly built together with shear walls. In high seismicity regions, constructing walls along the frame’s height is proven ineffective. Thus, in numerous studies, using at a certain beneficial, and this kind of structure popularly known as curtailed However, area above could suffer significant deformation under seismic load upgrading performance those upper parts needed. study, 2-dimension RC frame building improved by installing buckling-restrained braces (BRBs). The response performed through non-linear dynamic analysis an open-licensed software, STERA_3D. To determine ideal number location BRBs walls, classical genetic algorithm exercised Python language programming. parameters involved optimizations inter-story drifts, BRBs, damage indices surround frames. result shows that configuration resulted from optimization reduce excessive amount displacement height. Moreover, give fittest installation to upgrade partial
