[摘要] 本文對(duì)各種柱底嵌固基礎(chǔ)的抗彎剛度進(jìn)行了計(jì)算分析，并對(duì)設(shè)計(jì)經(jīng)驗(yàn)進(jìn)行了歸納總結(jié)，供設(shè)計(jì)參考。文章著重指出了一般基礎(chǔ)的抗彎剛度都很難滿足柱底嵌固的要求，這將使計(jì)算結(jié)果與實(shí)際結(jié)構(gòu)受力產(chǎn)生較大誤差，應(yīng)引起設(shè)計(jì)和理論方面的高度重視。

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
