what program are u using?
The Straus7 does it because is one element that you define and has no property, it only transform uniform surface load into uniform beam loads.
Maybe i have seen it in etabs, i will respond you soon if such a thing is possible with etabs.
I want to buy a software for designing every type of structure and these are the posibilities i have:
Sap2000
Etabs
Straus7 V2.3
Ansys 8.0
Algor
Could you please tell me which of these is the best?
Thank to everyone that will respond.
