Dear All,
In one of my project, I used ETABS package for lateral analysis. This is a 15 storyed structure and i got a fundamental period of 2.2 sec. The dimension of building is 150' x 150' and 150 ft height. This is just a square building envelope.
As per code, this is classified as flexible bldg & i have come out with gust factor = 1.05.
I took mass source as 100% self weight, 100 %super imposed dead load, 25 % live load.
Is the procedure right?
Can i consider this building as a rigid structure & take gust factor as 0.85 with a view of Height / min width < 4.0.
Please provide your inputs.
Thanks in advance
