| 摘 要： | 混合式交错桁架结构不宜用于高烈度地区,为了提高其抗震性能,采用ETABS分别对普通混合式和不同耗能段位置的新型交错桁架结构等4个算例进行弹性反应谱分析,提出了一种新型交错桁架结构?分析结果表明:新型交错桁架结构比混合式交错桁架结构有更好的抗震性能;耗能段设置在桁架上弦比下弦更为合理?

| Abstract: | A composite staggered truss structure is not suitable to be used in highly seismic region.In order to improve its seismic behavior,four examples including the common composite staggered truss structure and new staggered truss structures with the energy dissipation segment in different positions are analyzed by the elastic response spectrum analysis with ETABS,then,an improved staggered truss structure is brought up here.The results indicate that the seismic behavior of the new staggered truss structure is better than that of the composite staggered truss structure;The structure with the energy dissipation segment in the top chord is more reasonable than that in the bottom chord. |
