有箍筋钢筋混凝土梁的抗剪强度计算公式采用什么样的表达形式,是一个有争论的问题。对此有两种完全对立的看法,一种看法认为有箍筋钢筋混凝土梁的抗剪强度可以分成两部分,一部分是箍筋直接参加抗剪产生的抗剪强度Q_k,另一部分是混凝土部分的抗剪强度Q_h,并且混凝土部分的抗剪强度可以用无腹筋钢筋混凝土梁的抗剪强度近似地代替;另一种看法认为这两部分是不能分开的,它们是相互影响的,不能用无腹筋钢筋混凝土梁的抗剪强度来近似地代替有腹筋梁中混凝土部分的抗剪强度。大多数人同意上述后一种看法,理由是从有箍
The expression of the formula used to calculate the shear strength of reinforced concrete beams with stirrups is an issue of debate. There are two completely opposite views on this, one view is that the shear strength of a reinforced concrete beam with stirrups can be divided into two parts. One is the shear strength of the stirrups directly participating in the shear and the other is the part of the concrete. Shear strength Q_h, and the shear strength of the concrete part can be approximately replaced by the shear strength of reinforced concrete beams without reinforcement; another view is that the two parts cannot be separated and they are mutually influential and cannot be used without reinforcement. The shear strength of reinforced concrete beams is used to approximately replace the shear strength of the concrete part with web reinforcement. Most people agree with the latter view. The reason is that there is a
