Bridge seismic design manual

 · The substructure seismic-design process in the bridge modeler is documented in the Bridge Seismic Design manual. This manual, based on AASHTO specifications for LRFD bridge seismic design, describes the automated seismic-design procedure for bridges. Displacement-demand formulation is based on Article of the AASHTO Guide .  · Name: Bridge Seismic Design. Description: Automated seismic design of bridges based on AASHTO guide specifications for LRFD seismic bridge design.  · DESCRIPTION. CHANGES HAVE BEEN MADE TO INTRODUCE THE NJTA LOAD RATING MANUAL TO DESIGN ENGINEERS AND STIPULATE ITS USAGE FOR NEW AND REHABILITATION BRIDGE DESIGN PROJECTS. THIS REVISION ALSO CLARIFIES THE LOAD RATING ANALYSIS AND RESULTS WHICH SHALL BE INCLUDED IN THE PHASE C .
