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" …

Aug 31, 2025 · Hi, I am writing a calculator for sizing up free-standing masts for small boats, and I need to estimate their deflection at a certain load, and the breaking load to get a safety factor. …

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 31, 2025 · Many users have historically asked how to determine the deflection and rotation equations for a simple beam with a partially distributed uniform load (case 4 in table 3-23 of …

Feb 28, 2019 · Everything is looking okay, except for lateral deflection on one of the crane runway beams. The runway beam on one side is on the exterior gridline of the building and laterally …

Jul 29, 2014 · Hello all, I was hoping someone can shed some light on the topic of differential deflection of a crane runway beam for me. I have a situation where the runway beam on one …

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, …

Apr 13, 2011 · We have always designed our partition support beams to meet the strict deflection requirements for the wall, using the wall and floor live loads. Ive been using panelfold's criteria …

Mar 21, 2014 · I checked the truss software deflection, and it exactly matched the method of using only MoI of chord areas - to 3 significant digits. However I am doing a study in my spare time, …
