Bridge Division utilizes two types of prestressed concrete girders for the design of bridges: 1. AASHTO Shapes 2. Bulb-T Shapes Steel beams, welded plate girders and other special designs are used on an as needed basis. See the accompanying Prestressed Beam Reference Guide for beam reinforcing details, bearing pad details and a strand pattern guide. Beam Dimensions Standard beam dimensions for both AASHTO and Bulb-T beams are shown below.

Connection Details for PBES - Federal Highway Administration

The AASHTO LRFD Bridge Design Specifications [1] contain provisions for precast full depth deck slabs. Portions of those provisions will be covered in this example. This example will be for a full depth precast concrete deck slab placed on girders that run parallel to the span.

Frequently Asked Questions: Barriers, Terminals, Transitions , aashto standard roadway bridge connecting beam

W-Beam to Thrie-Beam bridge transitions may need to use the non-symmetric W-to-Thrie connector that keeps the top height of the entire rail at approximately 31 inches. In addition, there is no need to transition in height to many 27 -inch high terminals.

Guardrail Transitions - Safety | Federal Highway Administration

Almost all existing W-beam guardrail systems that connect directly to a bridge rail without adequate blockouts or a rub rail near the bridge connection should be considered unsatisfactory because they can result in vehicle snagging, which in turn can contribute to a catastrophic accident.
