# Equations for Indeterminate Continious Beam of 3 Spans

## Equations for Indeterminate Continious Beam of 3 Spans

(OP)
Hey everyone,
I am looking for refferences to solved equations interms of different loads and span lengths for continious beams with 3 spans. I see that my 13th edition of the AISC table 3-23 has 3 different uniform load cases, that gives coeficents. I need something like this, but for a transient uniform load of Length (L), and a transient point load (P). Is there any solved diagrams for these statically indeterminate continious beams. Looking for max deflection, and max moment as a function of span length, and load type & location.

That's what I was looking for, but in english language and US units . From what I could decipher from the language barrier, appears my load case isn't in the tables, bummer . Guess I'll have to model it with software. Thanks anyways.

### RE: Equations for Indeterminate Continious Beam of 3 Spans

What about reviewing the solutions to specific conditions in the AISC steel design manual? You could then put then into some spreadsheets.

ETA: and don't forget that you can combine cases (assuming the structure response is linear)

You could use software to generate your own tables. The spreadsheet linked below will do continuous beam analysis in whatever units you want:

ConBeamU 4.05 and ConBeampy 1.02
