I can’t seem to find a da6-beaam formula for partial UDL’s for a simply supported beam. Deflection You couldn’t use the delta-max equation for one, then superimpose the delta-max from the other, because they occur at separate points.

Can you account for cantilever moments too? Deflection Thank you all for your help, I have ordered roark’s book formuoas I feel that this resource will stand me in good stead.

AISC Beam Diagrams

You couldn’t use the delta-max equation for one, then superimpose the delta-max from the other, because they occur at separate points.

It might not be the “exact” maximum deflection, but it would be pretty close, and likely plenty precise enough for the application.

I doubt you’ll need one that is far off from the AISC tables. Can you post that beam for us? I think your two basic questions is a force near the edge or the middle more likely to break the beam; what effect does fixing the ends have are good physics questions, but the extra info about beam materials and properties is unnecessary, the physics answer to this problem will just assume an idealized generic beam.


Steve, the information your lookinf ofr is readily available from any basic textbook or on the web. Thanks for the feedback. For Part 2, beam clamped at both ends, use their figure I think you’re going to have to write some kind of program in Excel or whatever you’re using.

JAE, that sounds like the condition he’s looking for. Deflection Thank you for a swift response. Steel and concrete give better results, except for the uncertainty of the loadings.

Only if the the load put the beam beyond its elastic limit, but you knew that already. I initially thought of it not having any moment, and could’ve sworn da6-baem was the case, but then I was looking at some moment influence diagrams with hinges and that’s what caused me to pick an answer that didn’t have zero moment at the hinge.

Just draw it out please. Create an account or sign in to comment You need to be a member in order to leave a comment Create an account Sign up for a new account in our community. I hadn’t looked at figure 3 and assumed it only gave maximum deflections. Physics Stack Exchange works best with JavaScript enabled.

A lot of the times you can do a combination of multi-span cases, as in superposition, and the result is accurate. Zach Mierzejewski 7. Floris k 11 KyleOman Thanks, I removed it. Digital Transformation may be defined in a number of different ways by analysts or enterprise software vendors.

If I have a simple beam with two supports and a static load, does placing the load in the center push the beam closest to breaking catastrophic failure? The units will be determined by the units you use in your calculation. I think you’ll have to superimpose two load cases to get this one.

Thank you for helping keep Eng-Tips Forums free from inappropriate posts. I am a handy man who knows a little bit of da6-bwam, but no engineering. I thought those numbers might be relevant because I was trying to avoid getting “It depends.

How do you plan to account for that.

Defense manufacturing is all about project manufacturing and project accounting. Any other load configuration you can dream up – it’s probably in there too. The multispan ones were very helpful to me for visualizing moment and shear distribution. Time to do some last minute brushing up, get organized, and get lots of rest before the big day.

Yeah the problem was ; I had a general sense of the moment diagram for that case, without the hinge, when I first looked at it, but the hinge was what was throwing me off.

Home Questions Tags Users Unanswered. Deflection Are you looking for deflections for this load condition see attached??? Click Here to join Eng-Tips and talk with other members! Or you can just integrate it out yourself. Deflection Using something like Castigliano’s method. Use the deflection from Figure 3 in your attachment to get the deflection with load from zero to b. Typically on this site we won’t do ‘engineering’.

The Eng-Tips staff will check this out and take appropriate action. That said, here’s some wisdom from another old guy not me. I’m not sure I understand the relevance of before, during, and after UDL.
