I'm looking for a standard that defines deflection limits for overhang beams. To define what I mean here by overhang beam, please refer to this image. This post contains some mentions of max deflection of L/180, L/240, L/360, L/600 and other figures. This seems to me to apply to fixed-fixed...
Hi, I want to understand what deflection criteria I need to design to in a case where I have a rigid point (Core) with a beam at mid span adjacent and the minimum span over / gradient. Is there any guidance on it in Eurocode? Thanks
I am interested in learning of any experience with long term deflection of reinforced concrete beams or slabs that has resulted in problems, even if only appearance related. The ACI Code clearly requires consideration of long term deflection when deflection calculations are required. However...
I'm trying to determine how ETABs ver. 9.2 is reporting beam deflections. I have run my design and have a beam failing as a result of deflection and I can see the load combination which is resulting in that deflection. When I check the analysis moment 3-3 diagram and the deflections that...
I'm designing masonry slender walls using Enercalc and I always have concerns with what it's doing. The default load combinations for either IBC or ASCE for deflection include W only at 1.0. Which, as far as I can tell, is ultimate wind. Wall deflection should be at allowable levels, if I...
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.
