Spatial analysis of simply supported slab beam bridges strengthened with polymer carbon fiber material

In order to analyze the lateral distribution coefficients of simply supported slab beam bridges strengthened with polymer carbon fiber material accurately, Analytical solution of simply supported slab beam strengthened with polymer carbon fiber material under vertical half-wave sinusoidal load is deduced based on bond-slip theory and conditions of displacement compatibility. Force method equation of the method of revising hinged slabs for transverse influence line is deduced with deflection curve calculation formula which calculated by analytical solution. Analytical expression of the method of revising hinged slabs with regard to carbon fiber strengthening is obtained. The transverse influence line of the fabricated simply supported slab bridges assembly are calculated under vertical half-wave sinusoidal load based on above theory. And the lateral distribution coefficients of simply supported slab bridges are calculated with transverse influence line revised. It provides a simple and convenient practical calculation method for the practical analysis of simply supported slab beam bridges strengthened with polymer carbon fiber material.
