摘　　要：结合实际工程,通过多方案比较及反复计算分析,对照由普通网架大量抽杆后衍生的结构体系,从几何稳定性、传力路线、用钢量指标等多角度进行对比论证,并探讨将立体桁架用于中小柱距厂房的有关具体问题。By comparing the solutions and analysis, it is indicated that the geometric stability, load transfer way, steel dosage of the derived structure system from a common grid frame by removing its many members. It also is discussed how to use spatial truss in workshops with middle/small space between columns.
