THE ANALYSIS OF CALCULATION OF PUNCHING STRENGTH OF RC SLABS ACCORDING TO THE DESIGN CODES
分析了各国设计规范中钢筋混凝土板冲切强度的计算方法，通过实验与理论对比，证实冲切强度受纵向配筋率影响，配筋率越高冲切强度越大。
The article analyses the calculation of punching strength of RC slabs according to the design codes of various countries. The comparison of experimental and theoretical results is presented. Both experimental and theoretical research confirmed the dependence of punching strength on the longitudinal reinforcement ratio in the tensile zone. While the reinforcement ratio of the tensile zone is higher, the angle of punching pyramid sidewall is less, the critical section is far away from the edge of the column, the critical perimeter is longer and thus the punching strength of the slab is greater.
