3D FEM program only do AASHTO design checks, working for a state (like PennDOT) that has a supplementary bridge spec, makes software checks a chore and you end up doing it by hand anyway or trying to simplify the analysis so you can use a software solution, which defeats the purpose of...
DLBridge, Do you mean to ask what "Service" life is required for the bridge deck? It is correct to use the Class 2 exposure for this type of condition. Beyond this, AASHTO Bridge Design spec is pretty useless when it comes to practical design of concrete elements exposed to corrosive env...

The AASHTO Guide Specifications for Seismic Isolation Design (a.k.a., Guide Spec) contain simplified procedures for estimating the displacement and force demand imposed on a bridge designed to be seismically isolated. The Uniform Load Method in this document is a linearized method for estimating ...

I’m designing a long span pedestrian bridge. It's a multispan steel girder bridge. A computer vibration analysis shows a vertical frequency of 1.9hz which is less than 3hz which is less than the AASHTO allowable in the pedestrian bridge spec. AASHTO allows the frequency below 3hz if the...
