此页面上提供的信息旨在展示 CSA A23.3 条款的部分设计收敛性，可通过 SkyCiv 实现隔离基础. 所有示例均参考以下书籍:
书 1: Svetlana Brzev 和 John Pao. 钢筋混凝土设计: 一种实用的方法, 2009.
例 # 1 Design of Axially Loaded Isolated Footing
参考: 书 1, p.605.
描述
A typical cross-section of a square-shaped spread footing supporting a 500 mm square concrete interior column is shown in the figure below. The column carries a specified dead load of 1000 kN and a specified live load of 1000 千牛. The allowable soil bearing pressure is 250 千帕.

载入中
考虑两种静载荷情况:
\( \文本{d} = 1000 \文本{ 千牛} \)
\( \文本{大号} = 1000 \文本{ 千牛} \)
The results of service and factor load combination are in computed in reference of NBCC 2010.
分析
使用刚性常规方法进行分析. 见 隔离基础用户手册 有关使用 SkyCiv 基金会的更多说明.

笔记: Discrepancies on some values are due to the following:
*Actual self weight of column and footing are considered in SkyCiv. 此外, SkyCiv requires a column height greater than zero.
*SkyCiv calculates actual measurement of the effective depth for both directions.
SkyCiv Foundation module offers an innovative and user-friendly interface for the design and analysis of an isolated footing in accordance with CSA A23.3-14.
