[摘要] 本文对各种柱底嵌固基础的抗弯刚度进行了计算分析，并对设计经验进行了归纳总结，供设计参考。文章着重指出了一般基础的抗弯刚度都很难满足柱底嵌固的要求，这将使计算结果与实际结构受力产生较大误差，应引起设计和理论方面的高度重视。

Abstract: Focuses on flexural rigidity of various foundations at the bottom of columns, then summarizes all kinds of design experience for consideration. Emphatically points out that it was hard for the flexural rigidity of foundation to satisfy the demand of fixation of column bottom, which produces bigger error between calculations and actual forces. Finally, it was worthwlule to pay more attention in design and theory.
Keywords: frame culomn; foundation; fixing rigidity
