Development And Experimental Study on Domestic TJI Buck-restrained Brace

Abstract:

Domestic Q195/235 steel was adopted to produce a new type of buckling-restrained brace,TJI buck-restrained brace.The design and structural requirements of brace were proposed.Moreover,the performance requirements of steel core and testing standards of TJI buck-restrained brace were put forward,too.Cyclic loading test was conducted on TJI buckling-restrained brace.The experimental result shows that the buckling-restrained brace has better hysteretic characteristic and ability of seismic resistance,which is an effective member for energy dissipation.As a result,the ability for seismic resistance of structure improves greatly.
