工工程施工中 ,经常发现箍筋绑扎倾斜 ,与梁轴线不垂直现象 ,见图１。箍筋不与梁轴线垂直 ,便没有充分发挥箍筋的抗剪能力 ,并且在梁的端部 ,不能保证箍筋间距的准确。如此施工 ,没有完全达到设计目的。产生此种现象的原因是计算箍筋高度时 ,没有考虑现场当梁交叉时纵筋所占的
In engineering construction, it is often found that the stirrups are bound and inclined and not perpendicular to the axis of the beam, as shown in Figure 1. Stirrups are not perpendicular to the beam axis, they do not give full play to the shear capacity of stirrups, and the ends of the beam, can not ensure the accuracy of stirrups spacing. This construction, did not fully achieve the design purpose. The reason for this phenomenon is that the height of the stirrups is calculated without considering the longitudinal reinforcement occupied by the beam
