屈曲约束支撑是一种新型高效的钢结构支撑,也只一种耗能支撑。一方面可以避免普通支撑抗压承载力差异造成的缺陷,另一方面具有金属阻尼器的耗能能力,可以使主体结构构件在地震下基本处于弹性范围内。 Buckling restraint brace is a new and efficient steel structure support, also only a kind of energy-consuming support. On the one hand, it can avoid the defects caused by the difference of ordinary bearing capacity, and on the other hand, it has the energy dissipation capacity of metal dampers, which can make the main structural members in the elastic range basically under the earthquake.
