    I saw some variations of this question, regarding engineers working from outside the U.S. and engineers working on federal projects. But, what if the engineering work is done by the staff of a private owner with P.E.s licensed in the states in which the work is, but not licensed within the state...

    Design of variable web depth bridge girder (using AASHTO 6.10.1.4)

    I'm designing a deck plate girder for a railroad. We are keeping the existing piers and so I am minimizing the pier work by decreasing the depth of the girder at the supports. I've referred to AASHTO 6.10.1.4 "Variable Web Depth Members" for guidance and have calculated the Pv, Ph, fn that it...

    Load distribution of masonry plate

    I am trying to find the load distribution of the masonry plate of a spherical bronze bearing in SAP2000. I used the 'solid model-block' template to create a solid model of the 36"x36"x3" masonry plate. I changed the restraints along the bottom of the plate to rollers and applied a vertical...

    Strip Load surcharge on Sheet pile wall with sloped backfill

    I am doing analysis on a sheet pile headwall for a CMP culvert under a railroad. I have been looking but have been able to figure out how to determine the lateral pressure from a strip load surcharge when the backfill has a 1:2 slope. I orginally just used the Bousinesq formula, but because of...
