If the load is a downward load and not applied at a support then you will have a sagging bending moment. Watch this video -> ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-Xvg38nlxkOU.html
What is the maximum in inches that a typical 100 m vessel (bulk carrier) will be allowed to sag or hog? Just ANY value will do to give me an IDEA of some kind what the actual value would be. Would it be 24 inches? Would it be 2.2 inches? Or 0.05 inches? ANY VALUE that is realistic will do. All these videos repeat the same thing over and over with not a single value ever given.
Hi Daljinder. It depends on many factors such as location of the structural member, form of construction and site constraints. Ex: too much sagging may reduce headroom clearance under a bridge.
