    Looking for some opinions regarding local buckling of lips on cold formed steel C-purlins. The subject building is comprised of 10 inch deep C-purlins spanning (continuously via bolted splices) over girts spaced at 20' o.c. No bridging is installed in the building. Sprinkler pipes are...

    No Residential Building Code Adopted in Vermont?

    I am conducting a forensic investigation on a home in VT involving a heaving slab. When I went to the local jurisdiction's website to determine the adopted building code, I was unable to find any information. So I called the Zoning department (which handles residential building permits), and...

    Reduce Liability on Dead Project

    I did the structural engineering for a spec home several years ago. The contractor went bankrupt during construction, and now the bank has the property for sale. The basement of the house was completed before the contractor went under, so anyone who purchases the property will likely want to...

    Wind Loads on Retractable Solar Panels

    I am designing the foundation for an array of solar panels. There are four 15' x 18' panels attached to a continuous horizontal pipe support. Between each panel, there is a vertical column which connects the pipe support to the foundation. All four panels can rotate together about the...

    Restrained Basement Wall Design

    I know a lot of questions have been posted on this topic, but I still am unable to see a popular consensus: I have a very long rectangular building with a full basement (10' ceiling). There are no intermediate walls perpendicular to the long direction. The floor trusses run parallel to the...

    Masonry Wall on Slab on Grad

    Any recommendations for the capacity of a 4" concrete slab on grade to support a masonry (or any other material for that matter) wall? I have a client that would like to install a new 8" masonry mechanical chase in a commercial building. The wall is 10' tall. I would like to avoid saw cutting...

    Wood Header/Trimmer/King Stud Design

    When designing a wood header, what assumptions are made concerning the loading of the trimmers and headers? After sizing a header, I usually select the trimmers to provide adequate bearing area for the header and bottom plate, and assume the trimmer is taking the full gravity load. Thus, the...

    Compression in Wood Diaphragms Induced by Basement Walls

    When designing the floor framing and diaphragm for a typical residential basement (restrained design with walls laterally supported at slab and at floor), how are nonbearing walls adequately braced? I would think blocking would need to be installed between each framing member far enough to...

    Best State for P.E. Reciprocity

    Is there any one state who's P.E./S.E. license is recognized by all others? I am in the process of obtaining civil and structural licensure in Arizona, but if I do any work in other states in the future, it would be nice not to have to take their exams, and just obtain licensure via reciprocity.
