摘要
探讨了根据受弯构件在使用荷载下的裂缝情况来推断正截面承载水平的两种模型,从而得出了裂缝特征值、荷载和截面配筋率的相互关系。提出了简化计算模式,为钢筋混凝土受弯构件正截面承载力评估提供了一条新途径。
Two models assessing load level of the section according to cracks under working load Of reinforced concrete beams have been developed. The relation between the crack feature, that is, the even crack width over the even space of crack, the load and the steel ratio is also developed and a simple model was advanced . A new method of bearing capacity assessment of reinforced concrete beams has been proposed.
