钢筋混凝土梁身按设计需要贯通孔洞(特别是孔洞较大)时,以往作法一般都按经验计算。孔洞应做成圆形,并尽可能布置在梁的受拉区和剪力较小处,洞底距下部的最上一排受拉钢筋不得小于
When the reinforced concrete beam body needs to pass through holes (especially when the hole is larger) according to the design requirements, the conventional methods are generally calculated according to experience. Holes should be made round, and should be arranged as far as possible in the beam’s tension zone and the shear force is smaller. The bottom of the hole from the bottom of the top row of tensile reinforcement must not be less than
