摘要
对于承受反复荷载作用的钢筋混凝土受弯构件 ,设计中除要考虑产生的瞬时变形外 ,还要考虑产生的疲劳残余变形。介绍了随机反复荷载作用下钢筋混凝土受弯构件长期变形的计算和可靠度分析方法 。
In addition to the instantaneous deformation,there exists an accumulated permanent deformation for reinforced concerete bending element subjected to repeated load,which results in a larger long\|term deformation and should be taken into account in the design.Approaches for predicating the long\|term deformation of the element subjected to random repeated load and analyzing its reliability are proposed and an illustration example of a creane beam is presented.
