    Beam Theory vs Code Results

    Ben Floan
      In the static verification problems found in the online help, there is the "T" cantilever beam given. At the given length, 2000in, the results compare quite well with the beam theory which gives deflection = PL^3/3EI ~ 0.06%. However, if one shortens the length of beam from 2000 to 1000, to 500, to 250in error increases to 0.86%, 4.19%, 17.71% respectively. Why?.. is this a limitation in the code or theory (Euler-B vs Timoshenko)? Any input on this would be much appreciated.
