国产TJI型屈曲约束支撑的研制与试验

Development And Experimental Study on Domestic TJI Buck-restrained Brace

摘要:

采用国产Q195/Q235钢材开发研制了一种新型屈曲约束支撑,即TJI型屈曲约束支撑.给出了支撑的设计方法和构造要求,以及支撑芯板材料性能要求与支撑性能标准;对TJI型屈曲约束支撑进行了往复加载试验.结果表明,此种屈曲约束支撑具有很好的滞回特征和耗能性能,是一种十分有效的耗能构件,可以大大提高建筑结构的抗震性能.

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.
