Abstract:
In order to find out the distribution law of the effective flange width coefficient along the span under axial forces and bending forces, finite element analysis was performed and the formulas for calculating effective slab width coefficient under axial forces and under bending forces were derived. The results show that 28° is the desirable transmission angle of axial force caused by the axial compression of stay cables. The practical calculation method of effective slab width coefficient for large-span composite cable-stayed bridges under the combination action of axial force and bending moment can precisely reflect the stress of the concrete deck plate of composite cable-stayed bridge, and can provide references for the safety of the structure and the design improvement of composite cable-stayed bridges. 3 tabs, 9 figs, 12 refs.
