双向板的受力钢筋沿纵横两个方向布置,当同一部位(如跨中)两个方向的弯矩同号时,纵横钢筋必然重叠,为了增加较大弯矩方向的截面有效高度,双向板的构造规定,将较大弯矩方向的受力钢筋设置于远离中和轴的外层,另一方向的钢筋置于内层。这一规定在一般现浇板中争议较少,但在筏板基础的配筋中不应死搬教条执行。某四单元六层住宅楼,设计为筏板基
The two-way plates are arranged in two directions: the reinforcement bar must overlap when the same moment (such as across the center) in two directions of the same moment, in order to increase the effective height of the section in the direction of the larger moment, two-way plate The structure stipulates that the stress reinforcement in the direction of the larger moment is placed on the outer layer far from the neutral axis, and the reinforcement in the other direction is placed on the inner layer. This regulation is less controversial in general cast-in-place slabs, but it should not be carried out by dogma enforcement in the reinforcement of raft foundations.
