First, I am currently using Ram Concept version 3.1.1. I am wondering whether the current version support otherwise compared to the above mentioned version.
Secondly, as far I know, ram concept only allow for vertical static loads input not for dynamic seismic loads as well lateral loads
Thirdly, there is no option to import/export between Ram Concept and Etabs.
Fourth, Ram concept recommended not to model upper structures to the current slab design ==> ignore the stiffness of these elements
Fifth, To calculate the long term effects, we need to modify in Etabs in model analysis such as modulus, then do the different way to the Ram Concept as the different default values.
Sixth, the way of strip definition in Ram Concept is different to Etabs or Safe leading the different slab behaviour under actions.
Correct me if is am wrong.
Can't really compare myself to some1 who's used to using Ram concept as I'm still new at it,and I mostly learned how to use Ram Concept from it's manual and the help of some engineers.
have read a definition of seismic load and wind load in the manual of the software but it's not discussed throughout(manual of version 3.3).
why would u need the export/import between the Ram Concept and Etabs?(asking here for not knowing)can't we just use Etabs for designing the columns and walls including the lateral effects,and if we use finite element instead of strip method the behavior should be the same?,then use Ram Concept for the slabs.
you've got a point on lateral loads ,don't have much experience in the deformation of slabs due to lateral loads,what I know is that if the slab is a rigid diaphram it shouldn't deform under lateral loads.
now,since you are more experienced than me,what softwares do u recommend to use so that importing/exporting from Ram Concept can be done?
your effort and time writing back is highly appreciated.
