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". 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.

Beam Deflection | PDF

Beam Deflection | PDF 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 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". 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 elements and finishes. in this case, relative deflection (l/x) is usually the target. this limit reflects the local curvature or deformations at play.

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. Is anyone aware of any code mandated defelection restrictions for diamond plate (raised pattern floor)? aisc table 3 18a limits deflection to l/100 which results in an extremly low allowable load. i am analyzing a few existing industrial mezzanines to determine an appropriate load rating them. 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 general maximum wind deflections are in the order of l/400 to l/500. 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.
