| Abstract: | The energy variation method is used to derive the theoretic formula for effective distribution width of flange of the new type of GFRP composite beam under uniform linear load and the reliability of the formula is verified by finite element numerical simulation.With reference to the analysis methods for conventional steel and concrete composite beams,the parametric anal- ysis is further made in order to investigate various factors that affect the effective distribution width of the flange of the composite beam. |
| Keywords: | composite beam bridge flange effective distribution width mechanical behavior analysis |
