Aug 11, 2014  2. Multicell Box Girder. The transversal torsional deflection and bending torsional deformation of bridge girder due to transversal seismic action or lateral wind force may have great effect on bridge behavior [].For this reason, many researchers have paid much attention to the studies of torsional capacity, bending torque coupling effect, and loss of stability due to lateral inclination.

Reinforced concrete (RC) box girders are a common structural member for road bridges in modern construction. The hollow cross-section of a box girder is ideal in carrying eccentric loads or torques introduced by skew supports. This study employed acoustic emission (AE) monitoring on multicell RC box girder specimens subjected to laboratory-based torsion loading.

ANALYSIS OF COMPOSITE BOX GIRDERS

The methods of analysis and design of box girders have been surveyed several times to date(l.4,l.5,l.6). The prismatic folded plate theory by Goldberg and Leve(l.7) considers the box girder to be made up of an assemblage of folded plates. This method uses two-dimensional elasticity theory for determining membrane stresses

Torsional Analysis for Prestressed Concrete Multiple Cell Box

The softened truss model theory applied to a prestressed concrete multiple cell box is developed in this study. In this theory, the concrete torsional problem is solved by combining equilibrium and compatibility conditions and constitutive laws of materials. Until now the theory has been applied only to the case of pure torsion with a single cell section.
