[提要]  通过一实例的空间分析，说明了错列桁架结构体系的抗侧力特性。并对根据合成法简化而得到的平面结构进行了计算。结果表明，错列桁架结构体系可按文中的合成法简化成有支撑的平面框架进行抗侧力分析。

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
