陈才堡同志的“钢筋砼平板的抗剪强度”一文(本刊1986年第1期),对平板抗剪问题的破坏机理进行了较深入的分析,指出钢筋砼平板的冲切和抗剪是属于同一个性质的问题,可以合并研究,提出了适用于冲切破坏、剪切破坏及介于冲切、剪切破坏的平板强度计算公式。笔者认为,论文中的下列问题值得讨论。 1.作者虽然把冲切问题和抗剪问题当作一个整 Comrade Chen Caibao’s “Shear Strength of Reinforced Concrete Plates” (No. 1 Issue of 1986) carried out in-depth analysis of the failure mechanism of plate shearing problems, and pointed out punching and shearing of reinforced concrete plates. It is a problem of the same nature. It can be combined to study and formulate the calculation formula for the strength of the flat plate that is suitable for punching, shearing, and punching and shearing. The author believes that the following issues in the paper are worth discussing. 1. Although the author regards punching and shearing problems as a whole
