Continuous beam formula in Italian.

Continuous beam formula in Italian.

Continuous beam formula in Italian.

(OP)
Hi all,

Is any Italian-speaking engineer able to explain what the letters A1, B1 and A2,B2 represent in the attached diagram?
I can follow all the other headings but it's just those that fox me.
Thanks.

RE: Continuous beam formula in Italian.

I don't speak Italian, but I don't think you've included enough information for this to matter. I would guess they mean the end reactions calculated as if there were two simple span beams instead of one contiuous one. You could check this against the standard formulas for continuous beams over stiff supports.

RE: Continuous beam formula in Italian.

going from the formulas for the Ti's, looks like the A,B's are the simple span end reactions combined with the reactions caused by the interior moment, MI:
A1 = simple span reaction at the left end of the first span
B1 = simple span reaction at the right end of the first span
A2 = simple span reaction at the left end of the second span
B2 = simple span reaction at the right end of the second span

RE: Continuous beam formula in Italian.

yes, midspan reaction = B1+A2

another day in paradise, or is paradise one day closer ?

Many thanks all, cleared it for me!

RE: Continuous beam formula in Italian.

It looks like a pretty good listing of loadings for beams. Does anyone have an idea from what reference text this came from ?

RE: Continuous beam formula in Italian.

original book : "Stahl im hochbau" - Verlag Stahleisen - Dusseldorf - 1969 (but 1st edition 1935)
my copy (word by word translation in Italian) : "L'acciaio nelle costruzioni" - ediz. Cremonese - 1973 (out of print - few copies available on line)

PS : I already did (for my personal use) the digitalization of formulas for beams and frames. I can post if no problems with copyright : let me know

RE: Continuous beam formula in Italian.

german original text > translated in Italian > translated in English !

fortunately math is an international language !

RE: Continuous beam formula in Italian.

rb1957 : ... so what's the reason of this thread ?

PS : can I post or not ? or no need because of computers ?

RE: Continuous beam formula in Italian.

Italian is the proper language for engineering. All educated people agree on that. (wink paraphrasing from a fav movie of mine.)

RE: Continuous beam formula in Italian.

Robyeng, would be good if you can post. I'm from an Italian background and would like to see an Italian structural engineering reference.

RE: Continuous beam formula in Italian.

These kind of formulas you can find in most of the 'older' Engineering text books....

Ebook - Mastering Tolerances for Machined Parts
When making CNC machined parts, mastering tolerances can be challenging. Are general tolerances good enough? When does it make sense to call out for tighter tolerances? Do you need a better understanding of fits, datums, or GD&T? Learn about these topics and more in Xometry's new e-book. Download Now
eBook – How to Choose the Correct Corrosion Testing Method
When designing a metal component, engineers have to consider how susceptible certain alloys are to corrosion in the final product’s operating environment. In a recent study by NACE (National Association of Corrosion Engineers), it was estimated that the direct and indirect costs of corrosion in the United States is approximately 6.2% of the GDP. In 2016, that cost exceeded $1 trillion dollars for the first time. Download Now
