高烈度地区综合商业体内防屈曲约束支撑（BRB）施工技术

BRB CONSTRUCTION TECHNOLOGY AND APPLICATION IN INTEGRATED COMMERCIAL IN HIGH INTENSITY AREA

昆明春之眼商业中心施工中,为解决普通支撑受压屈曲及滞回性能差的问题,采用防屈曲约束支撑(BRB),在支撑外部设置套筒,使用焊接或螺栓连接及销轴连接等方式进行拼合,使抑制支撑的受压屈曲形成防屈曲支撑,达到消能减震效果,保证了工程质量.

To solve the poor compressive buckling and hysteretic performance of common support during construction of Kunming Chunzhiyan (Eye of Spring) Commercial Center, buckling-restrained brace (BRB) was used and sleeve was set outside the brace. They were connected by welding, bolting or pinning, to turn the compressive buckling into buckling-restrained support. Energy dissipation and shock absorption effects were realized and engineering quality was guaranteed.
