[提要]  通過一實(shí)例的空間分析，說明了錯(cuò)列桁架結(jié)構(gòu)體系的抗側(cè)力特性。并對(duì)根據(jù)合成法簡(jiǎn)化而得到的平面結(jié)構(gòu)進(jìn)行了計(jì)算。結(jié)果表明，錯(cuò)列桁架結(jié)構(gòu)體系可按文中的合成法簡(jiǎn)化成有支撐的平面框架進(jìn)行抗側(cè)力分析。

Through an example's spatial analysis, this article accounts for the resistance properties to lateral forces of staggeredtruss system. Then the simplified plane structure according to synthetical method is calculated. The result shows that the staggered-truss system can be simplified to the plane braced frame according to the synthetical method when lateral forces act on the system.
Keywords:  staggered-truss; lateral forces-resisting; synthetical method; simplified calculation
