屈曲约束支撑与TTD支撑经济性分析
屈曲约束支撑(Buckling Restrained Brace,简称BRB)作为具有良好耗能能力的新型支撑被广泛使用。与此同时,金属阻尼器发展迅速,也为结构抗震设计提供了新思路。将金属阻尼器与传统支撑(文中采用方钢管)结合设计出新型TTD(Tube-in-Tube Damper)支撑,其屈服承载力由阻尼器承载力决定,刚度由方钢管与阻尼器共同决定。改变长度与屈服承载力,设计对应的BRB与TTD支撑,对比两者用钢量,发现刚度与屈服承载力相当的TTD支撑相比BRB可节省用钢量,在承载力较小与支撑长度较大情况中尤其明显,这为地震作用下支撑设计提供了新的思路。...
