[提要]  介绍了采用冷轧带肋钢筋配筋的5根两跨等跨连续梁和6块两跨等跨连续板的试验结果，指出在设计这类构件时考虑塑性内力重分布的必要性，建议了合理的弯矩调幅值，并且用一个楼盖实例证明，按照给定的弯矩调幅值可以节省30%左右的用钢量。

Test results of R.C. continous beams and slabs reinforced with cold-rolling ribbed bars are introduced. The necessity in consideration of plastic redistribution of internal forces during designing these structures is illustrated. A moment adjusting value is proposed and the moment coefficients and shear coefficients of control sections of the structures under different load bearing conditions are provided. Finally, through the instance design of a reinforced concrete floor, the result shows that 30 percent of bars can be saved by using cold-rolling ribbed bars.
