Center of Mass
Center of Mass
(OP)
I know it seems very elementary , but i have problem and doubts ,
well i want to know , when im going to calculate center of mass in each floor , without any software , should i calculate the weight of walls ? walls at perimeter and partitions ?
and what about that half of the height of walls above and below each floor system , , i mean what about it , ? is it necessary to be regarded in CM calculations , cause if it is , the first floor will be different ,,,
Tnx
!!

I like to debate structural engineering theory -- a lot. If I challenge you on something, know that I'm doing so because I respect your opinion enough to either change it or adopt it.

... but i dont like to neglect ,
and about these partitions , why is that they say use uniform load , what about line load , i mean , is it wrong ?
RE: Center of Mass
Regarding uniform load treatment of partitions: it's just an approximation, like everything else that we do. Internal partition for many kinds of buildings often are quite uniformly distributed about the floor plan.

i really needed to know if surplus calculations are wrong are just to be more accurate , i was in doubt , ,
and by surplus i meant walls ))
okey-doke !
RE: Center of Mass
When I first start a project, I'll use AutoCAD to quickly trace out the floor plate as a mass and the perimeter of the building as a polyline. You can use AutoCAD's MASSPRPOP command to quickly locate the CM's for the floor plate and the walls seperately. If they're close, I don't worry about it. If they're not, I'll give it a little more attention.
