Hi, I'm having issues with a plate model on Staad.
I've put as "Selfweigth" a multiplier of -1 for global Y on all plates, but when I analize it, on the results section appears to exist a moment load, and the output for base pressure is weird.
Output for base pressure on selfweigth case (i suppose it's a bug or something, because the values are all 0.072):
Moments on selfweigth:
I attach the model here in case anyone can help me with this.Platea.std
Thanks in advance!
The moments that you see in the Statics Check Results table are the moments due the loads, calculated about the origin (0,0,0). So even if you have just gravity loads, you would see non-zero moments in the table as these are about the origin. However this does not mean that your mat is subjected to moments.
