- Description
- This module discusses the design of bracing systems for the superstructures of straight and curved girder systems. I-girder and box shaped members are covered. Bracing for other types of bridges, such as truss, arch or towers is not specifically addressed; however much of the information included in this module may be applicable. Bracing systems serve a number of important roles
in both straight and horizontally curved bridges. The braces provide stability to the primary girders as well as improving the lateral or torsional stiffness and strength of the bridge system both during construction and in service. Depending on the
geometry of the bridge, braces may be designated as either primary or secondary members.
The engineer needs to recognize the importance of the bracing systems and bracing member design for appropriates construction and in-service stages. This module provides an overview of the design requirements of the braces so that engineers can properly
size the members to ensure adequate strength and stiffness.
The module provides: a) an overview of bracing utilized for I-girders is covered, b) a discussion of the bracing systems for tub
girders, c) design requirements for the members and connections of bracing systems.

- Description
- This module focuses on the factors which influence and the principles of the design of bolted field splices. Factors that influence field splice design and layout are presented, including span layout, curvature, and girder properties. General design provisions are also addressed in this module, including flexural resistance provided by a bolted field splice at the Strength and Service limit states, as well as detailing considerations. Lastly, a thorough design example of a bolted field splice for a steel I-girder is provided, illustrating calculations for flange and web stress, splice plate design, and bolt design. Strength, Service, and Fatigue limit states are considered, and design checks are provide for tension, compression, and shear resistance of splice plates, fracture and bearing resistance of splice plates, and strength and slip resistances of the bolted connections.

- Keywords: bearing design ; steel bidges
- Description
- Steel bridge bearings may be divided into three general types: elastomeric bearings, high-load multi-rotational bearings, and mechanical bearings. The designer must determine which bearing type is best suited to cost effectively accommodate the design
requirements. This module provides practical information for efficient bearing design and detailing. The information contained in this module is drawn largely from the following two sources - NSBA’s “Steel Bridge Bearing and Selection and Design
Guide,” Highway Structures Design Guide, Volume II, Chapter 4 (HSDH Volume II, Chapter 4)) and AASHTO/NSBA Steel Bridge Collaboration, G9.1-2004 “Steel Bridge Bearing Design and Detailing Guidelines.”

- Bridge management ; Bridges
- Keywords: Substructure ; pile foundations ; Drilled Shaft Foundations
- Description
- While the main focus of the Steel Bridge Design Handbook is the design of steel girder superstructures, the overall design process associated with the design of substructures is equally important. This module provides an overview of many issues associated with substructure and foundation design.
Many factors influence the selection of substructure and foundation materials, types, configurations, positions, and orientations. Often, existing constraints will limit the range of options and intrinsically lead the designer to only one or a few feasible solutions. This module provides designers with an overview of several foundation types including shallow foundations such as spread footings, and deep foundations that utilize piles or drilled shafts. The module also discusses conventional, integral, and semi-integral abutments, and provides considerations for the design and detailing of these substructure components. Several
considerations for pier selection are also presented, including multi-column piers, single column piers, pile bents, straddle bents, and integral pier caps. Lastly, this module provides designers with information regarding substructure software availability,
seismic design, precast substructures, and superstructure and substructure interaction.

- Keywords: Steel Bridge ; Deck Design ; Concrete Deck ; Precast Concrete Deck
- Description
- The primary function of a bridge deck is to support the vehicular vertical loads and distribute these loads to the steel superstructure. This module provides practical information regarding the decking options and design considerations for steel bridges, presenting deck types such as concrete deck slabs, metal grid decks, orthotropic steel decks, wood decks, and several others. The choice of the particular deck type to use can depend on several factors, which may include the specific application, initial cost, life cycle cost, durability, weight, or owner requirements. For the deck types discussed herein, a brief description of the particular deck type is given, in addition to general design and detail considerations.
