Abstract:

Simplifying the flange of T simple-supported beam as the plane stress plate, an expression in closed polynomial form was derived based on the method of symplectic elasticity for the effective width of the T simple-supported beam under uniform or linear load acting on whole span. The solution of the effective width ratio from the expression under the uniform load was compared with the data in British Standard BS5400 and the result show that the obtained expression is correct, simple and effective, enriches the theoretical analysis and simplified calculation of the effective width in the T simple-supported beam bridge.
