This study employed acoustic emission (AE) monitoring on multicell RC box girder specimens subjected to laboratory-based torsion loading. Three multicell box girder specimens with different cross-sections were tested. The aim is to acquire AE analysis data indicative for characterizing torsion fracture in the box girders.

Refined analysis of curved thin-walled multicell box girders

1994-10-3  Abstract. The generalized Vlasov's thin-walled beam theory was combined with the finite element technique to develop a new curved thin-walled multicell box girder finite element which can model extension, flexure, torsion, torsional warping, distortion, distortional warping and shear lag effects. For multicell box girders, several distortional ...

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.
