Allowable deflection of beams | Eng-Tips 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 analysis That will tell you the vibration frequency, amplitude, etc and compare that to the allowable limits of the equipment
Deflection Limits | Eng-Tips 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 an l 360 delf limit for a particular beam comes out to be 1 45" I personally try to keep deflection for any beam under 1"
Allowable deflections for Residential Floor Beams | Eng-Tips 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 steel beams) I am trying to develop a list of criteria for younger engineers, and I would appreciate some input from some of y'all
Deflection | Eng-Tips 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" deflection such as floor "sponginess"
Deflection Formula | Page 3 | Eng-Tips 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 explanation, and the final expressions for deflection and maximum deflection for a simply supported beam under a uniformly distributed load (UDL) Click to expand
Deflection check | Eng-Tips 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, deflection is very readable from the ground, less so with composition, but still readable
Simple Deflection Question | Eng-Tips The code deflection limit charts for Floor Members simply states: Live load = l 360 Nothing for Wind D+L = l 240 So am I only checking the Live Load deflection and the Load combination (D+L) deflection? Does my Load combination of D+0 75L+0 75(0 6W)+0 75Lr not need to meet l 240? Or is
Brick Cladding Deflection Limits | Eng-Tips They pretty much don't spell out deflection out of plane They leave it to the engineer to calculate the deflection of the brick withe and compare it to stress - strain relations and geometric assumptions for crack widths When the brick is continuously - uniformlt tied to the backing, the deflection geometries must conform
Steel Stud Deflection Track Gap | Eng-Tips I guess just thinking about this some more, if my top-of-wall connection (deep leg slotted track or deflection clip) can only accommodate a portion of the deflection gap, would my other option be to size the stud to take a proportional amount of axial load to compensate for the remaining "total deflection"?
deflection limits | Eng-Tips Hello everyone, could you please tell me how we can define the deflection limits of (L or Lr, S or Wf, and D+L) as described in IBC Table 1604 3?
