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". 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.

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. 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. 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". 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 that aren't factored at all. for example: what are the appropriate combinations to used if i have both a floor.

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, such as in jetties or bridges, a deflection of the top of pile up to 80 to 150 mm is often tolerated. I am aware of the commonly accepted limits of 0.30" or l/600 for brick lintels, whichever is less. for very long spans the 0.30 requirement can be unreasonable. for example, a 40 ft. span truss that deflects 0.50 inches (l/960) has less angular rotation than a 15 ft. beam that deflects 0.30. With regards to the seismic load combinations utilizing the overstrength factor (asce7 05 section 12.4.3), i am trying to find guidance on appropriate deflection limits. i suppose there are two classifications of response, 1) code referenced and 2) sound engineering judgement. 1) i'm not. 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.
