摘要
对复杂边界条件下的钢筋混凝土板进行了试验研究,讨论了板的开裂、屈服与极限荷载。并根据钢筋混凝土分层法对板进行全过程非线性有限元分析,着重研究不同支撑条件与配筋对钢筋混凝土板的屈服线模式与承载能力的影响、板中加强带的作用与板的荷载-挠曲变形等。
This paper presents the experimental research on reinforced concrete slabs with complex boundary conditions, and the crack, yield and ultimate loads on slabs are studied. An analysis by nonlinear finite element program of reinforced concrete slabs has been made for the whole history of loading and effect of different supporting conditions and placing of steels on the yield line and the bearing capacity have mainly been investigated, as well as the function of the strengthening strip, deformation of slabs etc.
