摘　　要：根据方钢管混凝土构件受力分析的一般叠加法,分析了矩形钢管混凝土受弯构件的内力分配规律,推导出了其在正常使用状态下的刚度计算公式。为了验证分析结果的正确性,进行了4根方钢管混凝土的纯弯试验,通过对试验数据进行分析,上述的理论方法与试验结果吻合较好。该方法概念清楚,计算公式具有很好的实用性,并且为此类构件抗弯刚度的研究提供了一种思路。Based on the general superposition method for the members of square steel tube concrete,the internal force rules of rectangular steel tube concrete in bending are analyzed,a flexural stiffness formula is suggested in service states.In order to verify the validity of theoretical analysis,four specimens are tested,and the experimental results are better agreed with the theoretic method by analyzing these experimental data.The method is clear in concepts,the calculation formula is validity,and a new idea is given to the study on the flexural stiffness of the members of the rectangular steel tube concrete.
