Hello Ken, I am looking for the exact same formula as you were. Could you tell if you have finally found the answer? Thanks for your help.

ant00 Use superposition i.e. calculate with one load only then other and add results. I recall this principle from UNI so should be good. I also sent you reply by email Hope this helps KEN

Hi ken, I gone through path given by kelly, its related to beam supported at two ends, its fine. well, here its the formulas which you are looking for " Suppose, if I have a beam of span length 'l' and is fixed at both ends A and B and it carries two concentrated loads of W at C and D, each at a distance of l/3 from both the ends" Moment at A = -2Wl/9 Moment at B = -2Wl/9 Moment at C = Wl/3 Moment at D = Wl/3 Regards Darchi

Darchi & Kelly thanks for reply. Darchi - Would you have a general formula which gives loads at other than l/3 distance from ends i.e. at some distance "x" (both loads still symmetrical) Thanks again Ken Barnett

I found two point loads, and both ends supported at /beam_bending/beam_bending4.htm . and, /beam_bending/beam_bending7.htm For ends fixed (rigid(, I could not find that case in Roarks.
