[提要]  介紹了采用冷軋帶肋鋼筋配筋的5根兩跨等跨連續(xù)梁和6塊兩跨等跨連續(xù)板的試驗(yàn)結(jié)果，指出在設(shè)計(jì)這類構(gòu)件時(shí)考慮塑性內(nèi)力重分布的必要性，建議了合理的彎矩調(diào)幅值，并且用一個(gè)樓蓋實(shí)例證明，按照給定的彎矩調(diào)幅值可以節(jié)省30%左右的用鋼量。
[關(guān)鍵詞]  連續(xù)梁 連續(xù)板 內(nèi)力 重分布

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.
Keywords: continuous beam; continuous slab; internal force; redistribution; plasticity
