ETABS seems to ignore a part of the beam mass...

ETABS seems to ignore a part of the beam mass...

(OP)
I AM USING ETABS 8.15.  I HAVE DETECTED THAT ETABS, IN BEAMS ELEMENTS, IS ONLY CONSIDERING ONE FORTH (1/4) OF TOTAL BEAM
MASS WHEN ASSEMBLING MASS AT THE JOINTS.  IT SHOULD ASSEMBLE ONE HALF (1/2) OF THE BEAM MASS AT EACH JOINT.  WHAT IS GOING
ON? HOW CAN I FIX THIS PROBLEM? THANKS FOR YOU HELP.

P.D.  WHEN ASSEMBLING THE JOINT MASS FROM SHELL AND COLUMN ELEMENTS, ETABS DOES IT RIGHT, THE PROBLEM IS WITH BEAM ELEMENTS.

RE: ETABS seems to ignore a part of the beam mass...

Check the properties of the material you are using to the beams.

Also, I would recommend you to upgrade to the latest ETABS version.  It is 8.4.2 as of March 6.  CSI releases very buggy early versions that are polished as time goes by.
