摘要
以矩形钢筋混凝土双向板为研究对象,采用弹性理论方法,分析了三种不同边界条件下,双向板短边方向跨中弯矩小于长边方向跨中弯矩时两向跨度比值。并对这种跨度比的取值范围进行了详细讨论,给出了这种情况双向板的配筋建议。最后,以两对边固定两对边简支的双向板为例,讨论其截面配筋设计。得出有益结论,可为工程实际参考。
The two-way reinforced concrete rectangular slabs with three different boundary, conditions are investigated using elastic theory. The span ratios of the two edges for the midspan moment of the shorter edge is less than the longer edge are analyzed and compared. These ranges of span ratio are discussed in detail, and some suggestions about reinforcement are proposed. Finally, take two-way reinforced concrete slab with two opposite edges fixed and two opposite edges simply supported for instance and the cross-section reinforcement design is discussed. Some valuable conclusions are come to for the reference of the practical design.
