探讨外露式钢结构柱脚反力计算

Discussion on Calculation of Reaction Force of Exposed Steel Column briefly

由于现有钢结构设计文献均未详细阐述柱脚反力的计算方法,规范更是没有相应的计算公式。在设计实践中,设计人员缺乏相应的理论作为技术支持,这样不利于设计计算的修改和对计算结果的判断。基此,文章论述了外露式钢结构柱脚的反力计算原理,得出在不同条件下,锚栓拉力、混凝土应力的计算方法。

There is not specific description of calculation method and standard formula of the column base counterforce in the existing steel structure design documents. Therefore,for lack of the corresponding theory as technical support,it will go against the modification of a design and the judgement of the results of a calculation for designers. Here we discussed the calculation principle of exposed steel structure column counterforce,and concluded the calculation method of anchor tension and concrete stress under different conditions
