摘　　要：对冷轧扭钢筋配筋的二跨连续板结构荷载试验性能 ,特别是对冷轧扭钢筋配筋混凝土超静定结构的塑性内力重分布的特性及机理作了探讨 。By means of the experiment on the concrete slabs with cold rolled and twisted bars, the general situation of cold rolled and twisted bars is introduced in this thesis. The characteristics of redistribution of internal forces in reinforced concrete continuous slab with cold rolled and twisted bars is probed. The effect of the percentage elongation at maximum force and the surface spiral effect of cold rolled and twisted bars are expounded as well.
