( School of Civil Engineering, Hefei University of Technology, Hefei 230009, China)Abstract: The buckling restrained brace( BRB) has a good hysteretic behavior, which has the broad application prospect of element to serve as energy-dissipation. The application of BRB in seismic strengthening school building was elaborated and the whole structure integrity of pre and post strengthening was compared based on an actual project. The calculating results show that the strengthening measure by using BRB is effective in improving the seismic performance.
Keywords: buckling restrained brace; energy-dissipation; school building; seismic strengtherung
