Abstract:The design scheme of using profiled steel sheet - concrete composite slabs as the bridge deck for a pedestrian and non-motored bridge is analyzed, and the feasibility and advancement of applying this common building floor slab form in bridge structures are studied. By analyzing the special functional requirements of profiled steel sheet - concrete composite slab in bridge structures, and comparing the similarities and differences in structure and principle between it and the conventional steel-concrete composite bridge deck, the main design ideas are sorted out. Aiming at the special needs of non-motored vehicle loads and outdoor environment, the key indicators such as the longitudinal shear resistance, punching resistance and fatigue resistance of the joint surface of the profiled steel sheet - concrete composite slab are specifically analyzed, and its applicability is verified, providing a basis for the bridge design.
