Eric Williamson. 2016. Steel tub girders (trapezoidal box girders) are often used in straight and horizontally curved bridges due to their aesthetic potential .tee girders prove too heavy to transport and erect. Steel box girders have increased stability during erection in comparison to steel I-girders and may be appropriate for some locations. Rolled beam sections may prove more cost-effective than welded steel plate girders for shorter spans in remote locations. 15.1. General . 15.1.1.

The paper presents preliminary design considerations, including appropriate applications for steel tub girders; preliminary girder sizing and spacing guidelines; framing plan layout considerations; and suggestions related to preliminary .except for concrete box girder bridges, maybe analyzed as a curved spine beam. With regard to analysis,the LRFD specifications state that box girder beam superstructures have not been as closely examined with respect to approximate methods. Therefore, a dimensional model 3-was deemed to be required. b. For Closed Box and Tub Girder SteelSteel Bridge Bearing Guidelines Introduction. The purpose of these Guidelines is to present steel bridge bearing design guidelines and construction details that are cost-effective, functional, and durable. Four major types of bridge bearings are presented: 1.
