Cantilever Beam System Programs? 1

[samchrun]

Any body know of a good program out there to perform the design/analysis of Cantilever beams systems? Thanks,

Yes, a good mentor.

samchrun,

Could you elaborate on the issue of cantilever beam syatems? I'm not sure I follow your question as the statics appear to be elementary. Surely, you are not relying on a computer program to calculate the shear and bending moment of a cantilever...or are you? Perhaps you are concerned about stability issues. If so, please let us know.

BA-
I think he may be referring to "Gerber beam" systems.
I could be wrong as my knowledge on the topic is lacking.

ToadJ,

You may be right. I don't know of any good programs, but they are probably out there somewhere.

Most any general analysis program can do a continuous beam system with cantilevers and pins. Just need to model it correctly and apply the loads correctly.

I was introduced to it as the "Cantilever Span" method.

I don't know of any program that will move the hinges as part of the member selection.

Timing has a lot to do with the outcome of a rain dance.

Doesn't the AISC manual have a chart for the moments, reactions and cantilever dimensions at the end of the beam section?

samchrun,

There is an out of print publication from Canadian Institute of steel construction for Gerber Systems.
It may be available on the internet if you do a search.

I think you are referring to this link:

The OP asks for a computer program to design cantilever beams, an assumption is made that he is talking about cantilever and drop in beams for which he receives a lot of advice, he never responds, and somebody gives him a star. Go figure.

Thanks for all the input, for clarification I'm reffering to what I call "system of cantilevered beams" which according to the website posted by BAretired is also called a Gerber beam. In any case a program I used to do the analysis/design (Enercalc) a few years ago no longer has the module on their latest version. The program allowed my to model the exact beam configuration and also checked member stresses due to partial loading for continous beams.

Today they are all stars, they get a trophy for showing up, never mind actually doing something, or really participating.

Seems to me that one of the first rules of forums, OP’s and erudite questions, is never ask the question that you actually want answered, in a way that others will understand what you are really looking for and then be able to give a meaningful answer on, keep em guessin. This just eliminates the first 15 or 20 guesses and messes up the whole socializing and exchange aspect of the forum. Then promptly leave the discussion so as to keep em guessin. Gerbers first made baby foods I believe, then they got into the beam business when they realized that we structural engineers didn’t know what we were doing. Now they have canned programs (actually in small jars) which will spoon feed us beams and beans, many different flavors, but they all taste the same.
