Abstract:
Based on the hinge-jointed plate theory, combined with space grillage method and solid finite element method, authors analyzed the transverse load distribution calculating methods for the fabricated hollow slab bridges. Also, authors analyzed the differences between the calculation results of transverse load distribution, explained the causes of error, discussed the accuracy and applicability of each calculation method, then proposed reasonable suggestions. The study results show that the transverse load distribution factor of side plate is decreased and unsafe, without considering the sectional geometrical properties' differences between the side and medium plate; the calculation result of solid finite element method is accurate, compared with that, both of the hinge-jointed plate(girder)method and space grillage method are existing errors.
