在分析有关资料和总结工程设计经验的基础上,阐述了钢柱脚与基础刚性连接的外露式、外包式、埋入式、插入式四种柱脚的设计方法,并指出了四种固接柱脚的适用范围;分析了受力机理和抗震性能;介绍了相关的计算式和构造措施。文中提出的插入深度计算式已在工业和民用建筑中的单层、多层和高层结构工程设计中得到应用。 Based on the analysis of the related data and the experience of engineering design, the design methods of the exposed, outsourced, embedded and plug-in studs with rigid connections between the steel columns and the foundation are described. The applicable range of column foot; analyzed the stress mechanism and seismic performance; introduced the relevant calculation formula and construction measures. The proposed insertion depth calculation has been applied in the design of single-layer, multi-layer and high-rise structures in industrial and civil buildings.
