| 摘要： | The present research addresses many issues about the horizontally curved steel box girder bridges including: (1) Top lateral bracing systems with different arrangements; (2) Internal transverse bracing; (3) Coupled behaviors of lateral and internal bracing; (4) Intermediate external bracing between box girders; (5) Elastomeric bearings under horizontally curve bridges; (6) Ultimate strength interaction between bending and torsion; (7) Design requirements for longitudinal stiffeners for box girder flanges. Analytical and numerical investigations have been conducted on a number of hypothetical box girder bridges. Findings from these studies have been incorporated into design equations amenable to the AASHTO LRFD format. The validity and reliability of these newly developed equations have been verified by three-dimensional finite element analyses. |
