Area loads as a "virtual" shell elements. Can do IT??
Area loads as a "virtual" shell elements. Can do IT??
(OP)
Hi everyone.
I have a problem with loads in SAP2000.
I need to apply snow, wind and dead loads over a curved glazed roof. It's diifcult to translate a surface load, for example the snow into a frame distributed load, as I do in 2D frames, a in a curved surface (weight/surface ==> weight/lenght), bacause i can'nt cuantify the amount of forces that go to one beam, and the amount to the others
I heard it can be done asign the uniform loads to shells, but shellas only as "virtual elements" for only trassmission of forces, but no mass, moments, shears....
Can it be done?How?
Some help, please.

Once you have defined this 'dummy' area element, you can apply area loads and have it automatically transfer those loads based on tributary area and stiffnesses to the frame elements
You can call it a 'virtual' element or a 'dummy' element, but that's how you do it.
