柱下扩展基础受冲剪承载力计算的有关问题——函询《建筑地基基础设计规范》主编滕延京先生及其答复

Some Problems about the Calculation of Punching Shear Capacity of Spread Footing under Column——Consultation to and reply by Mr. Teng Yanjing,editor in chief of Code for design of building foundation

柱下扩展基础有三种可能的破坏模式,在一定边界条件以及配筋模式下,破坏模式是一定的;由发生冲切破坏控制而设计出来的扩展基础较为安全、经济。《建筑地基基础设计规范》主编——中国建筑科学研究院地基所滕延京研究员在给本文笔者的复函中,对此作了详细的解答。

The spread footing has three possible failure modes, to a certain boundary condition and reinforcement mode, the failure mode is certain; to design the spread footing controlled by the punching failure is relatively safe and economic. In the reply to author the detailed answers are given by researcher Teng Yanjing of China Academy of Building research, editor in chief of Code for design of building foundation.
