sap2000 area null
(OP)
I have a problem using area null
I draw a frame with hinges at the end of frames
I use area null and uniform to frame for slab load
Sap draw wrong bendng moments because they are not 0 at hinges
Thank you
I apologize for my English

RE: sap2000 area null
A null area is an area object which is assigned the None property such that it may be excluded from analysis, but used to apply area loads of type Uniform to Frame (Shell). This will ensure that loading transfers without the object contributing to structural stiffness. Check that auto-meshing is not assigned to these area objects, otherwise numerical problems may result.
did u use manual meshing instead of auto-meshing?
