(四)冲切设计计算 无梁楼板的强度有时不是受弯曲控制,而是受板柱节点的抗冲切能力控制。为增强其冲切承载力,可采用柱帽、托板和各种配筋加强措施,以下介绍冲切设计计算。 1.无粘结筋对抵抗冲切荷载的有利影响 如图10所示,当无粘结筋穿过柱头时,预应力在距柱面h_0/2范围内的垂直分量,必为作用在无粘结筋上的径向力所平衡,从而可得出某一方向的
(IV) Punching Design Calculation The strength of beamless floors is sometimes not controlled by bending, but is controlled by the punching resistance of the column nodes. In order to enhance its punching bearing capacity, column caps, pallets, and various reinforcement reinforcement measures can be used. The following describes punching design calculations. 1. Advantageous effect of non-bonded tendons on resisting punching load As shown in Figure 10, when no adhesive tends to pass through the stigmatic head, the vertical component of the prestressing force in the range of h_0/2 from the cylinder surface must be acting in the absence of The radial forces on the bond ribs are balanced so that a certain direction can be obtained
