摘　　要：通过对８个矩形钢管混凝土纯弯构件的试验研究，考察矩形钢管混凝土受弯构件的力学性能。试验结果表明，矩形钢管混凝土受弯构件具有较高的抗弯承载力和抗弯刚度，构件曲率延性良好。最后，比较了设计规程ＥＣ４、ＬＲＦＤ、ＡＩＪ和ＧＪＢ在计算矩形钢管混凝土抗弯承载力和抗弯刚度时的差异，所得结论可供有关钢管混凝土工程设计时参考。Eight concrete-filled RHS (Rectangular Hollow Section) members subjected to pure bending were tested. The behavior of the member is studied. The experimental results in this paper show that rectangular concrete filled steel tubular members subjected to pure bending have high bearing capaci- ty, excellent rigidity and good ductility. Finally, the difference of the calculation of the bearing ca- pacity and rigidity of the code EC4、 LRFD、 AJJ and GJB is compared. The achievements of this pa- per can be a reference for the design of concrete filled steel tube.
