Hi all!, im doing some research on Isolated Structures, in wich I had to model them on MATLAB software. In order to verificate my results, had to compare them with a comercial software, wich I choosed as SAP2000.
All values were okey, except for one: the Mass Moment of Inertia. I realiced that SAP2000 calculated this values as: m*(Lx^2+Ly^2)/4, but according to all literature its: m*(Lx^2+Ly^2)/12. And its important, cause the research has a highly important rotational behaviour.
When i used the (....)/4 value, my global results where identic to the SAP2000 ones, and now i have the doupt if sticking on to whats teorically correct (....)/12 or what appears to be correct from a well known and respected program.
Any help on this matter would be very greatfull. Thanks!
