Design And Construction

Because the multi-box girder bridge has many advantages, such as large torsion rigidity, large load-bearing capacity, stability, fine appearance, good applicability and convenient construction, it is widely used in China. But for the defection existing in design and construction, many box girders have serious diseases. Aiming at the diseases of a viaduct bridge, the causes of diseases are analyzed and the enforcement method is proposed in this paper. The study shows that, though the box girders have large torsion rigidity, the diaphragms are designed necessarily to enhance the transversal connection between the box girders, to make them bear the loads together, to reduce their stresses and deformation, and to reduce the stresses of deck too.

Girder Bridge

According to the definition about the positive and negative gradient temperature distribution of structural cross section in the Chinese bridge design specification of General Code for Design of Highway Bridge and Culverts (JTG D60-2004), same temperature loads are applied to beam model and solid model of a typical there-span prestressed concrete continuous box-girder bridge to compare the numerical results of thermal stresses calculated from the two finite element models. The beam model is built through professional software Doctor Bridge that is prevailing in China for structural static analysis of bridge design, while the solid model is built using ANSYS. Between the two models, the numerical results of total thermal stress regarded to be added up with self-restrained stress and secondary stress are compared. The results from solid model are found to be much more conservative than from element model. The identity and diversity of the two series of results and the reasons for the generation of the diversity are expounded. It is recommended that the thermal stress calculated from solid model be better to be taken into account in a design so as to examine or amend the results that calculated through the professional software based on bar system FEM theory.

Design And Construction

PC box-girder bridge with corrugated webs is a new kind of bridge, which named by the thin steel webs replacing thick concrete webs. It is applied abroad in China recently, which attracts attention for its shearing property. Because of lacking relative design and construction code interiorly, the related data of Mi-Luo-Jiang bridge was used in the study with the software ANSYS 10.0. The shearing property and bucking stability of Mi-Luo-Jiang bridge were studied and a theory was verified: corrugated webs do not bear moment and axial force. Besides, the result that the decisive parameter of shearing property of Mi-Luo-Jiang bridge should be allowable shear stress is obtained. The other study had been done on buckling stability of box-girder bridge with different corrugated shapes, maintaining other parameters invariant. Finally, the optimal scope of lateral plane length is [0.2,0.4], and the optimal scope of folded angle is [20º,50º]. The parameters used in Mi-Luo-Jiang bridge is verified as the best value. This study is meaningful and the results can be applied in the design and construction of the same type bridge.
