【摘要】 以K6型网壳为研究对象,考虑网壳支承结构的弹性效应,并在支承结构中设置屈曲约束支撑(BRB),考虑在9度区强震作用下,通过不同的屈曲约束支撑布置方式对结构进行动力弹塑性分析.结果表明,在考虑整体网壳支承结构共同工作时,结构主要节点位移和杆件内力响应都有所减小;网壳上部结构设置屈曲约束支撑能够有效降低节点位移和杆件内力响应;考虑上部和下部设置屈曲约束支撑共同工作对于K6型网壳减振耗能有很好的效果.更多还原

【Abstract】 The overall K6 reticulated shell structure’s dynamic elastic-plastic analysis in 9 degrees area under earthquake was researched under different places of Buckling Restrained Braces(BRB) on the shell.The elastic effects of supporting structure and Buckling Restrained Braces were considered as two key factors.Analysis result shows that,when the supporting structure works together,the structure’s response of displacement and internal force decreased markedly.After setting BRBs on upper shell,the displacement and internal force also decreased effectively,and it is good for energy consumption on K6 reticulated shell considering setting BRBs on upper and lower structures together.更多还原
