The design example includes detailed design computations for the following bridge features: conc rete deck, steel plate girder, bolted field splice, shear connectors, bearing stiffeners, welded connections, elastomeric bearing, cantilever abutment and wingwall, hammerhead pier, and pile foundations.

These design examples accompany a four-day training course that presents the theory, methodology, and application for the design and analysis of both steel and concrete highway bridge superstructures.

The steel girder design criteria are obtained from Figures through (shown below), from the concrete deck design example, and from the referenced articles and tables in the AASHTO LRFD Bridge Design Specifications (through interims).

For this steel girder design example, a plate girder will be designed for an HL live load. The original Highway Structures Design Handbook was produced by US Steel in the s. The project was subsequently taken over by AISC. The project was subsequently taken over by AISC.

Now, with federal grant money, FHWA, NSBA and HDR Engineering (principal engineer) have completed updating the Handbook. Structure types included in this book are built of concrete, steel, and wood.

Standard Specifications for Highway Bridges3 specifies the HS Live Load as the design live load for bridges designed under Allowable Stress Design (ASD) and Load Factor Design (LFD).

Please refer to these specifications for details of this design load. HS is used in Load Rating when calculating the Federal Inventory and Operating. Eurocodes. It gives two worked examples, one for a multi-girder bridge and one for a ladder deck bridge.

It is a companion to a publication giving general guidance on composite highway bridge design. The guidance in this publication has been developed from earlier well-established guidance in a number of SCI bridge design guides.

An outline for basic steps for concrete bridge design is given in Appendix A5 of the LRFD Specifications. This design example tries to follow this outline as closely as is relevant.

Also examines bridge history and development, materials, and loads. Demonstrates design procedures and development, the organization of design computations, and the interpretation of AASHTO design specifications. Includes discussions of substructures, bridge piers, abutments, and bridge rating and repair.

Steel bridge design (FHWA LRFD Design Example for Steel Girder Superstructure Bridge) (Backup: NSBA Two-Span Design Example) Steel bridge load rating by LRFD/LFD/WSD HW#2: (both of them assume Fy =50 ksi, fc’=4 ksi, modulus ratio = 8, rebars are in 2 / ft at mid-height of the slab).

Both were classroom teachers in structural engineering. At the time, a number of major changes were taking place in the design of highway bridges.

Philosophically the most dramatic was the change from a deterministic (allowable stress) design approach to a probabilistic (limit state) design concepts. Steel is a versatile and effective material that provides efficient and sustainable solutions for bridge construction, particularly for long span bridges or bridges requiring enhanced seismic performance.

Strengthening Methods for Noncomposite Bridges Noncomposite steel girder bridges will usually have symmetrical steel sections, that is the neutral axis is at mid-height of the Size: KB.

The piles will be end-bearing on relatively shallow bedrock. Our firm has traditionally used Allowable Stress Design for similar projects.

The structural engineer has provided us with loads and load combinations to be used in the LFD design. My understanding is that by October LRFD design of all bridges with federal funding will be required.
