摘要

将2根矩形钢管直接焊接形成新型T形钢管混凝土组合构件。进行了10组共20个T形钢管混凝土组合构件的抗弯试验,研究了它们在纯弯及压弯状态下的力学性能,分析了含钢率、剪跨比、截面尺寸、轴压比等对新型T形钢管混凝土组合构件抗弯性能的影响,最后比较了新型T形钢管混凝土组合构件和传统T形钢管混凝土组合构件抗弯性能的优劣。
This paper puts forward a new type T-section concrete-filled steel tubular composite member which was welded directly by two rectangular steel tubes,presents an experimental study on flexural behavior of 20 T-section concrete-filled steel tubular composite members and studies their pure bending and compressbending properties.The analysis is conducted about the effects of steel ratio,shear span ratio,section dimension and axial compression ratio etc,meanwhile the flexural behavior between the new type and the traditional T-section concrete-filled steel tubular composite member is compared.
