摘　　要：在典型的荷载工况作用下,对不同柱距三台五线一跨和三跨无站台柱雨棚做了对比研究。研究以雨棚的单位面积平均用钢量为主要控制指标,对比分析了工字型实腹钢梁+单钢管混凝土柱形式的雨棚分别在15 m、18m、24 m、27 m共4种柱距情况下的优劣性。结果表明,当一跨雨棚柱距为15 m或三跨雨棚柱距为15 m时,三台五线无站台柱雨棚在结构造型、安全性能等方面表现优秀,且平均用钢量最省。The no-platform-column of different column-span under typical load condition was eontrastively studied. The total steel quantity per unit area was chosen to be the main index to evaluate the canopy of I-section beam ＋ concrete filled steel tube column, whose column-span could be 15 m,18 m,24 m and 27 m. The results shows that when the column span of the single span canopy is 15 m,or the column span of the three span canopy is 15 m,the appearance,safety performance of the no-platform-column canopy of three platforms and five lines are more outstanding and at the same time the steel quantity is more economic.
