EATB vs RAMSS

[hawaiioption]

anybody tried both of them? As I know now there is no ASCE 7-10 wind load created by ETAB and even in 7-05, you have to input Gust factor which is hard to calculate for high-rise building. is my observation right?
Also the building period from these two programs are different: does ETAB consider column for the lateral contribution, but RAM does not if you don't specify them as lateral columns? Thanks.

ETABS consider columns for lateral combination, while RAM has the option between lateral/gravity columns.
Calculating gust factor is not that difficult, once you have a spreadsheet coded.

ETABS has a higher learning curve and is more suited for complex buildings, but RAM has its strengths in being user-friendly and providing easy-to-understand outputs.

Thank you, that means techanically for a shearwall system, you should design that moment in the column and slab-col conecction detail due to the lateral force even without considering chapter 21(ACI318) in ETAB? And no need for RAM result if not name it as lateral columns. Thanks
