Aug 3, 2001 · Dougantholz - It seems that deflection limits are up to the engineer who is designing, and not to exceed the limits set forth in code (l/240, l/360, l/600, etc.). Lets just say …

Oct 21, 2025 · Here is the complete solution for the given beam deflection question, solved using the double integration method. The attached pages show the full derivation, step-by-step …

Feb 1, 2013 · The proper Global deflection limit to use also has to do with what is on the roof as a roofing material - this looks like a rafter/beam situation is why I mention it. If the roof is tile, …

Jan 13, 2011 · I have a question regarding Structural Deflection Limits. The way I see it, there are three ways of going about it - Follow the IBC verbatim, or use ASD load combinations, or load …

Oct 21, 2009 · Deflection criteria are put in place for a variety of reasons, including aesthetics, limiting cracks, mitigation of creep, and to force sections to be more resistant to "dynamic" …

Oct 4, 2019 · It depends what the goal of the deflection limit is. For most deflection limits in structures, the end goal is either user comfort or preventing issues with non-structural …

Apr 16, 2012 · Are you looking at wind deflection or seismic? 0.02H is for seismic and your window wall would be damaged (but shouldn't fall off the building) in a seismic event. Most …

Jun 25, 2020 · Do the deflection criteria for the beam (L/240 for total load or 1" is what I'm using) depend on the deflections of the supporting girders? For example, if the midspan deflection of …

Sep 30, 2018 · I thought about applying double cantilevering to minimize the material for a small structure, but I don't seem to find a standard formula for the deflection of this beam (see figure …

Mar 27, 2025 · I am designing a canopy for a small stadium in an open field. The cantilever beams are w24x76 . They are 36 feet 10 inches long and 14 feet apart. A fixed end support on …
