摘要
根据某框架结构加层改造抗震加固实例,指出了防屈曲支撑在某框架结构加层改造抗震加固设计中优势及其布置方法,分析了防屈曲支撑在小震下的刚度贡献和中震及大震情况下的耗能情况,分析结果表明防屈曲支撑在框架结构加层改造抗震加固中具有良好抗震性能。
The advantage and layout method about buckling-restrained-braces in the seismic strengthening of storey-adding reconstruction of frame structure was pointed out according to the seismic strengthening of storey-adding reconstruction of frame structure in practical engineering.Besides,the stiffness of the buckling-restrained-braces to the structure was analyzed in minor earthquakes,and energy dissipation was analyzed in medium earthquakes and great earthquakes,which show that the excellent seismic behavior of buckling-restrained-braces in the seismic strengthening of storey-adding reconstruction of frame structure.
