Combined with the research and projects status at home and abroad,based on the Exquisite museum project,the newly-developed Domestic TJ-Ⅰ Buckling-Restrained Braces(TJI BRB),adopted domestic low yield point steel(LYP160MPa),Q195,specially made low yield point steel(LYP225MPa) as the core material,were presented in this paper.By a series of experimental research and theoretical analysis,we refined the existing conformations constantly,and ascertained the reasonable design procedure,which facilitated the application of the TJI BRB with greater yielding force that will be implemented in exquisite museum.Ten specimens,whose yielding forces are 400kN,900kN,1200kN,1300kN,1600kN,1800kN separately,are selected from the low cyclic loadings tests carried out in the building structure laboratory in Tongji university.By the summary of the test phenomenon and theoretical analysis,we can observe the steady improvement of the property of the specimens clearly.The TJI BRB,as the eventual experiment results indicated,illustrated steady hysteretic properties and outstanding fatigue characters,which are competitive to the parallel oversea products and is deemed as an effective damping device.By the adoption of the domestic low yield point steel,the research result can promote the application of the low yield point steel in aseismic engineering.
