    AI in your business

    Perhaps "calculated" was not the term I should have used. It searched the tables listed in the IBC and then gave me my answer based on the tables. However, this is exactly what I would love for AI to do. Find the values in the tables that I need and possibly provide exceptions where applicable...

    AI in your business

    I wonder if you had put "ultimate" if it would know better. I asked it to give me wind pressures based on the 2012 IBC and it calculated them perfectly. Saved me some time looking up the coefficients from the tables. Is there possibly another software that you could upload a pdf of the code to...

    AI in your business

    I have been wondering the same lately. Would it be possible to have chatGPT or another AI software read through a building code and provide a design based on inputs? Would it be able to consider exceptions to simplify design? The thought gets me excited, but I do not know how to "program" it to...

    EnerCalc Load Combination

    I also have only ever known 1.6. I'll reach out to them. I agree. I appreciate the sanity check!

    EnerCalc Load Combination

    I'm running a calculation in Enercalc with ASCE 7-16 as my reference code, and it's showing the controlling load combination to be 1.20D+L+0.20S+E+1.90H. This is an underground structure so the 1.90H is killing me. I can't find this load combination in ASCE, IBC, ACI, or AISC. Does anyone know...

    Water Main 90 Bend

    Typical 8" ductile iron water main serving one street. I was under the same impression that's what they're made for. No real constraints in the area from other utilities or structures. I'm leaning towards individual preference as well, but wanted to make sure I haven't been specifying plans...

    Water Main 90 Bend

    I'm being told that I can't use a 90 degree bend for a new water main. I've stated that we will use thrust blocking, but I'm required to use 22 1/2's instead to make the turn. Is this just a jurisdictional thing or is it bad design to use a 90 with thrust blocking?

    SAP2000: Resultant moment increasing with larger members

    The front portion you are seeing is a porch area with three front posts as support. The structure is all wood with plywood sheathing. The controlling load case is actually the roof live load case, which surprised me because I'm designing this for 160 mph winds. My best guess at the localized...

    SAP2000: Resultant moment increasing with larger members

    I believe the variable I'm overlooking that you've touched on is that, in a 3d model, there are additional lateral restraints in and out of the plane. I believe I'm right in saying that this is what's causing the internal force increase. The stiffness increases and is therefore the more...

    SAP2000: Resultant moment increasing with larger members

    Thank you for your response! I agree with you completely that it makes sense from a theoretical standpoint, but I can't make sense of it from a mathematical standpoint. I am simply considering if I look at a 2D structure that no matter the stiffness change, each member will experience the same...

    SAP2000: Resultant moment increasing with larger members

    I have a 3D model of a storage shed that I'm designing in SAP2000. I'm having trouble wrapping my head around the results I'm getting. The typical section view is a standard frame with a gabled roof (one stud on each side, pitched truss connecting them.) There is a significant wind load acting...
