【摘要】 对屈曲约束支撑铰接框架结构体系特点和抗震性能进行分析,并进行一个足尺屈曲约束支撑铰接框架结构模型模拟地震振动台试验研究。通过试验,分析不同强度地震作用下屈曲约束支撑铰接钢框架结构的动力特性、加速度反应、位移反应和破坏特征。振动台试验和研究结果表明:在强地震作用下(加速度峰值为1.20g),屈曲约束支撑交接框架结构层间位移角为1/100,屈曲约束支撑有明显的屈服变形,但没有发生屈曲现象,且整体结构中框架梁、框架柱仍保持弹性状态。理论和试验表明:屈曲约束支撑铰接框架结构可以在地震区使用。更多还原

【Abstract】 Characteristics and seismic action of hinge-connected steel frame with buckling restrained braces was analyzed.A full-scale model of hinge-connected steel frame with buckling restrained braces was tested on the shaking table.The dynamic characteristics,seismic responses of the structure were recorded and analyzed.The analyses and test results indicate that the buckling restrained braces behaved well,and under super strong motion earthquake(peak value of acceleration is 1.20g),the drift of the model was only 1/100 and the columns and beams without obvious damage.The hinge-connected steel frame with buckling restrained braces can be used in seismic area.更多还原
