Abstract: This paper analyzed the carriageway slab of ribbed slab bridge with sonic common dimensions by means of the finite strip method in high orders, and compared the results with that obtained by current design methods inland and abroad. On this basis authors proposed the rational simplified formulas to calculate this type of structures.

Key words: ribbed slab bridge, carriageway slab, effective distributed breadth, finite strip method, moment coefficient of correction
