Celt83: Good catch. Once I include the chord rotation parameter in the slope deflection equations to account for deflection at points B & D, how do I solve for that parameter? So far, I have 5 unknowns (rotations at all 5 points) and 5 moment equilibrium equations. But when I add in the 2...

Hi, Attached is an example problem in which I am trying to use the slope deflection method to determine moments in the indeterminate beam shown. The beam consists of a W12x50 (EI) with a W14x53 (1.38 EI) used from point B to point D. The problem I am trying to figure out how to handle by hand...

Got it. So I'd still calculate fixed-end moments on each side of the flange transition whether at a support or not and calculate rotations at each transition as well as at supports, then finally calculate moments at ends of each beam segment?

Great, thanks. For some reason, I always had a hard time remembering moment-distribution method. I always liked slope-deflection method. If you were to use slope-deflection, how would you handle a flange transition in mid-air (not at a support)? I know at supports, you'd break the beam up into...

Are commonly published indeterminate beam formulas for continuous beams only for use with a constant cross-section? I assume so. When you have varying cross-sections as in many steel bridge plate girders with flange transitions, you can't just simply apply these common equations, correct? You'd...

I think I'm starting to realize that I may not want to be a structural engineer for a very long time. Being on the outside looking in during college and while job searching, I really though I would like it but now I'm finding it to be a little different than what I expected. I'm finding I may...

Thanks for all the input guys.

Hi, I have been a bridge engineer for about 6 months now at my firm and for a short time at a previous employer. Now that I am working in a multi-disciplinary environment, I'm finding that my interests are broadening rather than being focused on one thing (bridges) as before. I've been thinking...
