钢筋混凝土双向叠合板抗剪强度的极限分析

Limit Analysis of Shearing Strength for Two-Way R.C. Laminated Slabs

通过对８块无结合筋双向叠合板的试验研究，本文采用组合周界错动机构，锥面母线为直线与曲线的连线，按塑性极限分析的方法推导了抗剪强度计算公式。该公式与试验结果符合性良好。

By experimental study on 8 two-way composite slabs without binding reinforcement, a method in which a staggered mechanism for combined periphery is adoped and the conical element is a conneceting line of a line and a curve is proposed. Also, a calculating formula for shearing strength is derived according to the theorem of plastic limit analysis, and this formula is in good agreement with the test results. \ \
