Jul 2, 2019 · Deflection in beam design implies relatively slow (nearly static) deflection of a beam. A beam subjected to vibrations means that you need to be looking into a dynamic or vibration …

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 …

Apr 27, 2009 · I have been pondering allowable deflection limits for our residential design standards for high-end residential *FLOORS BEAMS*(wood framed with LVL, glu-lam, and …

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, …

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 12, 2023 · The member deflection results will tend to report the RELATIVE deflection of the beam compared to its end points. So, if the beam is simply supported between two girders …

Oct 28, 2015 · Hey guys, Why are deflection limitations specified as a fraction of the span length, such as L/360 or L/240? I'm having a hard time picturing this criteria, it apears to be more of a …

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 …

May 8, 2012 · Hi folks, When Checking for serviceability of beams do you take the absolute deflection (meaning the deflection of the beam + the deflection of the supporting beam/girder …

Feb 6, 2003 · The allowable deflection can be different for diff structures as already pointed out by the earlier replies. My own experience shows that for piles with a long unsupported length, …
