柱下混凝土扩展基础的设计问题探讨

On design of reinforced concrete spread foundation under column

根据现行GB50010—2002《混凝土结构设计规范》和GB50007—2002《建筑地基基础设计规范》要求,对钢筋混凝土柱下扩展基础设计中存在的问题进行了探讨,推导了基础高度和基础底板配筋的计算公式,使基础的设计更趋合理.

This paper focuses on the problem of spread foundation under column of reinforced concrete by applying the code for design of concret structure（GB50OlO-2002）and the code for design of building foundation（GB50007-2002）, and the formula is inferred which is used to calculate the height of the foundation and distribution of steel bars of the foundation, as a result, it makes the design of foundation more rational.
