| Abstract: | Adopted domestic Q195/235 steel to produce a new type of buckling-restrained brace. Namely, TJI buck-restrained brace. The design and structural requirements of brace have been given, moreover, the performance requirements of steel core and testing standards of TJI buck-restrained brace have been put forward, too. Cyclic loading test has been conducted TJI buck-restrained brace. The experimental result indicated that the buck-restrained brace has better hysteretic characteristic and ability for seismic resistance, it is a valid member for energy dissipation and improve greatly the ability for seismic resistance of structure. |
