Steel reinforced concrete column comprising inner steel pipe
The invention discloses a steel reinforced concrete column comprising an inner steel pipe, and belongs to the technical field of composite structures in civil engineering. The steel reinforced concrete column comprises an inner steel pipe; the outer truss comprises a plurality of chord members extending in the axial direction of the inner steel pipe, a plurality of closed integrated annular web members arranged in the axial direction of the inner steel pipe at intervals, a plurality of horizontal web members connected with the chord members and the inner steel pipe, and a plurality of diagonal web members connected between every two adjacent integrated annular web members; the concrete wraps the inner steel pipe and the outer truss and is filled in the inner steel pipe; and the reinforcement cage surrounds the outer truss and is wrapped in the concrete. The inner steel pipe is high in pressure resistance and good in ductility; rod pieces of the outer truss are crisscrossed, the shear-resistant self-locking effect is achieved, meanwhile, the hooping effect of steel pipe confined concrete is reserved, it can be guaranteed that the concrete and the profile steel work cooperatively without additional shear-resistant connecting measures, the outer truss and the inner steel pipe are combined to form complementary advantages, a space structure system has large rigidity and stability, and the material consumption is reduced.
本申请公开了一种包含内钢管的型钢混凝土柱，属于土木工程中组合结构技术领域。型钢混凝土柱包括内钢管；外桁架，包括多根沿内钢管的轴向延伸的弦杆、多个沿内钢管的轴向间隔开布置的封闭的一体式环形腹杆、与弦杆和内钢管连接多个水平腹杆和连接于相邻两个一体式环形腹杆之间多个斜腹杆；混凝土，包裹内钢管和外桁架，且填充于内钢管内；钢筋笼，包围外桁架布置，且包裹于混凝土内。内钢管抗压能力强，延性好；外桁架杆件纵横交错，具有抗剪自锁效应，同时保留了钢管约束砼的套箍效应，能够保证混凝土与型钢协同工作而无需附加抗剪连接措施，外桁架与内钢管组合形成优势互补，空间结构体系具备较大的刚度和稳定性，节省材料用量。
