中文摘要	为研究复合钢管高强混凝土构件的受弯性能,完成了8个试件的静力试验。结果表明,试件跨中挠度达到其跨度的1/18时,除个别试件外,承载力均尚未下降;增大方钢管的壁厚或增大圆钢管的直径,都可提高构件的受弯承载力和弹性抗弯刚度。采用简化纤维模型(条带法)计算试件的跨中弯矩-挠度关系曲线,采用叠加法计算试件的受弯承载力,两者所得结果与试验结果均符合良好。; To study the flexural behavior of composite-sectioned high strength concrete filled steel tubular( CSCFT) members,static test of 8 simple-supported specimens was performed. The test results indicated that even the mid-span vertical deflection reaches 1 /18 of span,the flexural strength of most specimens does not drop yet. Increasing the wall thickness of square steel tube or increasing the diameter of circular steel tube could increase the flexural strength and the sectional elastic bending stiffness of CSCFT members. The mid-span moment-deflection curves of specimens calculated by the simplified fiber model has good agreement with the test curves. The flexural strength of specimens calculated by superposition method also has good agreement with the test results.
