Hi!
I have a doubt!
I´am modeling a group of buildings (three buildings whit diferents heights and shapes , they have a comon basement (it is the parking lot) like a table, when i did the modal analisys and checked the global base shear (on the comon first floor of the three buildings) and then i compare whit the sum of the shear of the colums the sum of the colums are greater than the global base shear. I did a simple model like a table and two towers ( 4 columns and 2 story) and i did the same comparisons and both values are equal bot when a did the same model with two tawers one whit 2 storys and the other with 3 storys the results are different (like the big model).
Can you help me?
P.D. Sorry for the bad English
