DC,
Kt can be found in Table A.3.3 in both the 2010 and 2015 Aluminum Design Manual. In the 2010 version, it has a table all its own, but in 2015 it is combined in the table for nominal strengths for each alloy, in the right-most column. Another thing to note--kt is not always 1.0. One...
Bearcat,
In Section E.2.1, Section C.3 is referred to, which indicates that all members that participate in the stability of a structure shall have an effective length factor of 1.0. I would take this to mean that cantilevers do not fall into this category, and fixed-end columns are to be...
Bearcat,
I am familiar with the 2010 and 2015 ADM, although I have not used any versions prior to this and am unfamiliar with their format. The 2015 version moves toward a style of code that resembles the AISC Steel Construction Manual in general format, and breaks down the limit states for...
I should also state why I believe they list engineering stress. I think it is because when we calculate stresses due to loads (what we compare to Ftu, etc...) we are using section properties of the original cross-section. It think it becomes a reference issue--we could also calculate stresses...
Sorry, I guess I didn't explain my question very well. I was referring to how design codes treat listed Ultimate Stresses--Ftu, for instance, say for a sample of 6063-T6 aluminum, which is 35 ksi. Is this 35 ksi an engineering stress value (as in, force divided by original cross-sectional...
This may be a novice question, but are ultimate stresses (tensile, compressive, etc...) that are listed for materials in design codes (such as the Aluminum Design Manual, Timber Design Manual, etc...) engineering stresses? I have always assumed that they are engineering stress because that is...
