第一节单向板的计算钢筋混凝土楼盖有装配的和现浇的两种。楼盖的结构形式有单向板肋形楼盖,双向板肋形楼盖和无梁楼盖等。楼盖由楼板及支承它的结构所组成,支承楼板的结构可以是梁,也可以是墙体或柱子。图1、2、3是几种常见的形式。图1表示楼板支承在相互垂直交叉的梁上,受力情况随长边l_2和短边 The calculation of the first section of the one-way slab The reinforced concrete floor has two kinds of assembled and cast-in-place. The structural forms of the floor cover include one-way slab ribbed floor slabs, two-way slab ribbed floor slabs, and beamless floor slabs. The floor cover consists of the floor and the structure that supports it. The structure that supports the floor can be either a beam or a wall or a column. Figures 1, 2, 3 are several common forms. Figure 1 shows that the slabs are supported on beams that cross each other perpendicularly, and the force conditions with the long side l_2 and the short side
