框架柱正截面设计时最不利内力组合的选择

The Choice of the Most Unfavorable Combination of Internal Forces on the Frame Column

对钢筋混凝土柱正截面设计的内力组合提出一种简化计算方法,根据柱的受力情况,分别从非抗震、抗震组合和大、小偏心受压两方面进行计算,并与已有的组合方法进行对比,得出该法适用于大、小偏心抗震组合情况,能保证满足抗震设计的配筋要求,对实际工程具有重要参考价值。

This paper presents a cross-sectional design of reinforced concrete columns simplified method for calculating internal forces combined.Based on the force column,respectively,from the non-seismic,seismic combinations and large and little eccentric compression of both calculated and combined with the existing method of comparing the results of the method is suitable for large and little eccentric seismic combinations.It also can ensure the seismic reinforcement requirements,and the actual project has important reference value.
