本文概述了159块钢筋砼板(配置或不配置抗冲切钢筋)及基础的冲切试验结果,阐述了板和基础的破坏形态和特征,讨论了影响冲切强度的主要因素,并提出了这类构件冲切强度的计算方法。按此方法计算所得值与国内外试验结果的符合程度较好。
This paper summarizes the results of the punching test of 159 reinforced concrete slabs (with or without anti-punching reinforcement) and the basis for the failure modes and characteristics of the slabs and foundations. The main factors affecting the punching strength are discussed and proposed. This kind of component punching strength calculation method. The results calculated by this method are in good agreement with the domestic and foreign test results.
