| Abstract: | 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.In this paper,in accordance with the results of the relevant theoretic derivation and finite element calculation,the calculation formula for the load transverse distribution factors of the composite bridge composed of pultruded GFRP decks and I-shape longitudinal steel beams are discussed and the problems of transverse internal force distribution of the bridge are thus resolved. |
| Keywords: | GFRP composite beam bridge load transverse distribution factor calculation method |
