Reistent bending moment calculation
Posted: 12 May 2023, 10:32
Good morning,
I have a problem in the evaluation of the resistent bending moments of the RC cross sections of a flat frame.
Concerning the modelling of the reinforcements, for each span I introduced 3 different cross sections (left and right bearings and midspan)
I checked manually the values calculated by Seismostruct and I noticed that:
- the resistent bending moment calculated in the midspan is the correct one;
-the two values of the resistent bending moment at the bearings are wrong (they're calculated exactly as in the midspan, but the procedure is not correct as they should have been calculated considering the upper reinforcements as tensed ad the lower ones as compressed).
How can I solve the problem?
Best regards
