    Costs of not renewing PE licenses in remote states

    Hello, I left my corporate firm 4 months ago and started my own engineering practice. Over the course of my career at previous firms, I became licensed in about 20 states, mostly due to one-off projects. My licenses in some states where I'm pretty sure I will likely never do work again are...

    Building Code deflection limits perpendicular to joist/truss spans

    Thank you Dauwerda for citing this discussion: "Ron posted a very similar discussion a few years back, here." Do you (or anyone else on this post) have the contact information for Ron (or even just a last name)? I'd like to discuss my scenario with him. Great discussion - I'm hoping for more...

    Building Code deflection limits perpendicular to joist/truss spans

    Thank you everyone for posting responses. Regarding this comment from Daywalker, "The 'tough sell' comes in when you have to tell a homeowner that the visible hump in their floor meets code, so they have no legal leg to stand on to make the builder fix it." This is the case I'm making - that...

    Building Code deflection limits perpendicular to joist/truss spans

    The IBC Floor and Roof deflection limits are frequently applied in the following manner for wood framing. The deflection of each floor joist or roof truss is checked to meet L/360 for Live Load, and L/240 for Total Load (I know the roof limits can be different, but for simplicity and for...

    Wind Loads on Solar Panels Generally, and Open-Roof Structures Specifically

    Thank you r13. I think the rendered image with the solar panels is a little difficult to see the underlying structure clearly, but there is no discrepancy in the array. Both the rendered image and the isometric image were generated from the same Revit model, and the brace is consistent...

    Wind Loads on Solar Panels Generally, and Open-Roof Structures Specifically

    Thank you for everyone's comments - I think designing as an open structure with a Kzt value for a cliff face in Exposure C is appropriate. Per Aesur's request, the array is over a courtyard created by two existing L-shaped buildings. The array is supported on arches spanning over the...

    Wind Loads on Solar Panels Generally, and Open-Roof Structures Specifically

    First, the general questions: I'm calculating solar panels over roofs in Phoenix, Arizona using ASCE 7-16 provisions, and am relatively new to using ASCE 7-16 for solar arrays. I'm calculating the LRFD average wind pressure normal to the panels to be around 35 psf to 40 psf. I'm determining...
