This artical takes a certain dust collection supporting concrete frame which is at 9-degree seismic fortification zone as the research object. A scheme using BRB buckling constrained support dampers for seismic energy dissipation technology, meanwhile another traditional seismic structural scheme is designed respectively for this supporting frame. PERFORM-3D assessment analysis software is used to calculate the elastic-plastic time history seismic dynamic force of the two structural models, and the seismic performance of the two design schemes is compared. The results show that buckling constrained braces have an effective energy dissipation and seismic reduction effect on this supportign concerete frame. The total earthqueke actions and story lateral drift ratio for structures using seismic reduction are distinct lower than non-seismic reduction structures under multiple or rare earthquake.Energy dissipation structure has better seismic performance and greater safety margin. Compared with non-seismic reduction structures, seismic energy dissipation structure has less engineering quantity and better economic benefits.
