摘　　要：通过对柱脚传力机理进行分析和柱脚的有限元计算,分析得出基于一维杆件平截面假定的柱脚纵筋的计算公式适用于传统外包式刚性柱脚,并对新型柱脚的设计提出了建议,对类似工程构件的设计具有一定的指导意义。The paper analyzes the pedestal＇ s transfer mechanism and undertakes the finite elementary calculation of the pedestal, indicates the calculation formula of the pedestal＇ s longitudinal reinforcement based on one-dimension member＇ s plane section assumption is fit for the traditional outsourced stiff pedestal, and provides suggestions for the design of new pedestal, so as to have the direction significance for the design of similar engineering components.

关 键 词：柱脚 有限元 平截面假定 刚度
