## wind load for robot 2011

In Concrete Building CBS , we can get automatic wind load on a concrete tower i.e high rise concrete storey building - why this option is not valid in robot 2011 as we can find in etabs program , it will save times

Hi
in robot wind loads are available automaticly
define the code in 'preference'
loads
others loads
wind/snow 2D/3D

many thanks for helping but I am talking regarding to generate automatic wind load for concrete high rise building ... it is not available in robot as Etabs
because etabs generates the wind load automatically and assign to the C.G of each floor

Hi
first step :you have to define the load cases DL,LL,TL...
2nd :you assign a values of each load case then go to #2 and generate your combinations...

If you draw a concrete building wind load will not be generated automaticlly I am sure
you have to assign it manually
Thank you

Automatic wind loading is always dangereous. That way, an engineer doesn't have any controls on how a load is created. In fact, Eurocodes are very general if it concerns external pressure coefficients. Mostly they do not correspond with real situations. The EC's are that unclear that some countries doesn't have a closing NAD.

I suggest you use the option of cladding and a surface load which will spread the wind load very well. You can choose if some intersecting bars need to be ignored in the trapezoidal distribution of loads or not. That way you choose on your own which cp coefficient to use on your wind load.

Would you please show example for contruction!
Thank!

Does cladding distribute wind loads onto slabs (C.G.)?
Is it possible the loads are being distributed as horizontal loads on the edge beams?
