Embodiment
[0028] The invention is a novel high-performance steel-UHPC sheet composite structure system and an interface connection technology adapted thereto. The structural system mainly includes the UHPC sheet 2 laid on the steel beam 1, and its interface is connected by a combined shear member welded on the steel beam 1, and the combined shear member is welded by a steel plate support 3 and a large-diameter short nail 4 Formed, the steel plate support 3 is a trapezoidal block, and the short nails 4 are arranged on the inclined plane and the two ends of the steel plate support 3.
[0029] The oblique short nails and the short nails at both ends adopt large short nails with a diameter of 30mm.
[0030] The length of the hypotenuse of the steel plate support 3 meets the diameter of the short nail and welding requirements, and the thickness of the steel plate support is determined according to the length of the hypotenuse and the inclination angle.
[0031] The bridge deck adopts UHPC s...
