The existing seismic capacity of the structure were calculated, and by analyzing the testing results, several strengthening methods were taken, such as changing structure shape, enlarging section, reinforcing with carbon fiber and adding constructional columns, and it can provide references for similar project.Keywords: the bottom frame structure; seismic identification; reinforcement measures
