摘要: 扩展基础的高度受抗冲切承载力控制,在设计时一般采用试算法,由此确定的基础高度可能较大,不经济且计算过程复杂。根据基底尺寸大小,分别推导出扩展基础受抗冲切承载力的基础高度计算公式;案例计算表明,利用给出的计算公式不需要进行试算,计算结果经济、安全,计算过程大为简化。

Abstract: The thickness of a spread footing is controlled by the punching stress. A larger than necessary footing thickness is usually resulted since the trial and error method is involved and this method is also cumbersome. The new procedure for determining the footing thickness for the punching failure mode for various footing dimensions is presented in this paper. The new method has the advantages of simple calculation and also resulting in an economical and safe footing design.

Key words: Spread Footings, Punching Failure Mode, Design Optimization
