Design Examples Recommended LRFD Guidelines for the Seismic Design of Highway Bridges

The ATC-49-2 report, Design Examples, was prepared by a joint venture partnership between ATC and the Multidisciplinary Center for Earthquake Engineering Research (MCEER). (Published 2001, 260 pages plus CD containing complete database).

ABSTRACT: The MCEER/ATC-49-2 Design Examples report contains two design examples that illustrate use of the Recommended LRFD Guidelines for the Seismic Design of Highway Bridges.

These design examples are the eighth and ninth in a series originally developed for the Federal Highway Administration (FHWA) to illustrate the use of the American Association of State Highway and Transportation Officials (AASHTO) Division 1-A Standard Specifications for Highway Bridges. Each of the nine design examples, including the seven previously developed, were carried out and reported on in a consistent manner, using the same calculation and report formatting procedures. Design Example 8 was performed on a five-span continuous cast-in-place concrete box girder bridge and the ninth design example (Design Example 2LRFD) was performed on a three-span continuous steel girder bridge. The design examples contain flow charts and detailed step-by-step procedures, including:

• Preliminary design;
• Basic requirements;
• Determination of seismic design and analysis procedure;
• Determination of elastic seismic forces and displacements;
• Determination of design forces;
• Design displacements and checks;
• Design of structural components;
• Design of foundations;
• Design of abutments; and
• Consideration of liquefaction
