圆桩承台冲切承载力分析

Analysis of Punching Shear Bearing Capacity of Pile-cap

假定钢筋和混凝土均为理想的刚塑性材料,根据塑性极限分析方法,推导了圆柱承台冲切承载力上限解,给出了圆柱承台受冲切承载力计算系数图,并与实验结果加以比较,吻合良好.

Assuming the materials to be ideal rigid-plastic, an upper limit solution of punching shear bearing capacity for pile cap is obtained based on the method of plastic ultimate analysis. The calculated results coincide precisely with the practical measurements.
