In this paper,we deduce the method for calculating the load distribution coefficient at the binding site of the holding nails of the products so as to calculate exactly the nail-holding strength of micron w.

The load transverse distribution coefficient of some special structure point is calculated by flexibility method.

Considering the change of the load transverse distribution coefficient along the bridge span,the maximum value of shear force at supporting point caused by uniformly distributed lane load is calculated by integral method.

Applying synthetically the principle of three methods:(a)increasing coefficient method of interal force in section;(b)load transverse distribution coefficient method for rigid jointed plat bridge;(c)method of equivalent span of simple supported beam,the calculating model for integrative type of reinforced concrete continuous slab bridge with cantilever flange is established.

The calculation of the new type of GFRP composite beam bridge can be made by approximately converting the spatial issues of the bridge into the plane ones by means of load transverse distribution concept and the theoretic analysis of load transverse distribution factors of such type of the bridge will be then carried out.

A calculating model which can determine directly the load transverse distribution factors of simple supported skew beam bridges is established.

Based on an analysis of the mutual action of GFRP deck and I-shaped longitudinal steel beam,different parameters of the influence on transversal live-load distribution factor are analyzed.
