摘要: 运用现场测试和有限元模拟分析两种方法，比较分别配置冷轧螺旋钢筋、光圆钢筋和冷轧带肋钢筋的楼板在正常使用状态下的工作性能，即开裂情况、挠度和应变等结构反应。结果表明，冷轧螺旋钢筋混凝土楼板的工作性能优于配置其他两种钢筋的楼板，建筑工程中用冷轧螺旋钢筋作受力钢筋是经济、可行的。

Abstract: By using field testing and finite element method, structures' responses of floors respectively reinforced by cold-rolled spiral steel bars, plain round bars and cold rolled ribbed steel bars were compared under the normal working loads, which were floor's craze status, deflection and strain.The results show that the performance of the floor reinforced by cold-rolled spiral steel wires is the best among three floors, and what's more, it is economical and feasible to choose cold-rolled spiral steel bars as stressed steel bars for building engineering.
