I have the following observations:
1) ETABS support suggests to use plane-stress elements to model shear walls. My question is why not shell elements when their element is free from membrane locking problem ?
In reality any wall will undergo some out of plane displacements. In...
Normally I use shell elements to model walls. I do not remember if etabs had mentioned anywhere in the manual on the use of frame elements to model the walls.
If it is there it must be a modeling option provided to the user. For example consider a situation where in you have a column very near...
You please refer to any finite element book to understand the difference between membrane, plate and shell elements.
ETABS permits you to use shell element to model the walls. Using the stiffness reduction options one can simulate only the membrane action of the walls.
Thanks for the responses.
ETABS permits application of different reduction factors for membrane and bending stiffnesses.
Lateral analysis of flat-plate structures was traditionally based on equivalent beam methods, using manual / simplified frame analysis techniques. The width of equivalent...
I performed lateral (wind load) analysis for a 24 story
shear walled flat plate structure as per ACI 318-99
clause 10.11.1. All the floors are post-tensioned slabs.
Plate bending elements were used to model the floor slabs
and walls in the 3D computer model. I used a reduced
floor slab...
