摘要
本文对《混凝土结构设计规范》(GB 50010-2010)中提出的矩形截面柱的阶形基础在柱与基础交接处以及基础变阶处的受冲切承载力计算公式进行了改进,使之成为形式非常简单、计算十分方便的一个表达式,只要将基础底板的外伸长度(S1)乘以冲切高度系数(λ)便可得到基础的有效高度(h0)。即使在CAD技术得到非常广泛应用的今天,此法仍可在初步设计阶段、施工图校审阶段以及在施工等阶段发挥较好的作用。
This article made an improvement of the computational formula of punching-bearing capacity of the stepped foundation of the rectangular section at the connection point of pillar and foundation as well as the step changing spot of the foundation mentioned in the Concrete Structure Design Codes,and made the formula as an expression which has a very simple form and very convenient to calculate,the effective height of the foundation（ho） can be got only by multiplying the stickout length（S1） of foundation plate by punching height coefficient（λ）.Even if in today＇s world where CAD technology is widely used,this method can still play a better role in the stage of preliminary design,the stage of proofreading working drawing and the stage of construction.
