Deflection | Eng-Tips
Oct 21, 2009 · 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 …
Deflection Limits | Eng-Tips
Aug 3, 2001 · 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 …
Modifying cantilever beam deflection and breaking load equations for ...
Aug 31, 2025 · Hi, I am writing a calculator for sizing up free-standing masts for small boats, and I need to estimate their deflection at a certain load, and the breaking load to get a safety factor. The masts …
Is the 0.6 wind load reduction(ASD) just to check deflection?
Nov 12, 2013 · ASD is not just for deflection checks. ASD is to check the capacity of the member (allowable stress for wood, allowable strength for steel) against the expected load. If you're using …
Why use different moment of inertia in deflection calc in ... - Eng-Tips
Aug 29, 2005 · ACI and PCI basiclly deal with same material, i.e. concrete, why in ACI, Ie=0.35Ig or 0.25Ig is used in calculating the member or slab deflection. While in PCI, the gross Ig is used in …
