ETABS Floor Slab – Shear Wall Compatibility

Floor Slab – Shear Wall Compatibility

This example, Figure 3, illustrates a 3D Concrete Flat Plate Building with shear walls and

an elevator core. Again, in this model, Line Constraints automatically appear at the lines

where the floor and wall objects intersect. This, of course, as in previous examples, will

enforce displacement compatibility when mesh geometries do not match. As shown in the

deformed shape of the Elevator Core, in many places the wall meshing does not match

the floor meshing. All elements meeting at common edges, however, still show no

displacement incompatibilities, even though the element nodes do not coincide.

Shear Wall – Spandrel Transition

This example, Figure 4, models a Shear wall – Spandrel System, illustrating mesh

transitioning from the spandrel to the shear wall. Line Constraints are generated as

needed in any direction. In this case the Line Constraints are vertical as well as

horizontal.
