(核工业第二四建设公司核电工程公司 海盐县 314300)[提要] 结合工程实例,在钢柱柱脚设计中利用混凝土握裹力代替混凝土承压力,使钢柱柱脚由传统柱脚简化为由插筋、连接板和安装螺栓组成的无底板柱脚,取得了较好的经济效果。

The design method and selection of -the footing elements are introduced in detail to engineers. Comparing with traditional column footing, this structure has better economic effect in some respects.
