本文引用钢筋混凝土双向板的塑性铰线理论,较系统地研究了六桩承台的抗弯强度,即承台弯曲破坏时的极限承载力,推导了六桩承台弯曲破坏时的抗弯强度上限解,给出了简易的计算方法及供设计计算使用的简明表格。用现有的试验结果加以检验,符合情况良好。 This paper refers to the theory of the plastic hinge line of the reinforced concrete two-way slab and systematically studies the bending strength of the six pile caps, that is, the ultimate bearing capacity when the cap is bent and destroyed, and deduces the flexural strength of the six pile caps when they are bent and destroyed. The upper limit solution gives a simple calculation method and a concise table for design calculations. Tests with existing test results are in good condition.
