Definition of Line Hinges for Ceiling Slab on Shear Wall

Helpful Questions & Answers

  • Frequently Asked Questions (FAQs)

I have modeled a ceiling slab supported on a shear wall. The shear wall should only absorb axial forces. So I have inserted a line hinge between the surfaces and defined it the way that the hinges are available for all internal forces except for those in the ux direction.

Although there is no hinge defined for ux, the plate deforms without being supported by the shear wall. Where is the error?

Answer

In this case, a line hinge is the right structural element to define the connection between the individual surfaces. The release definitions of the line hinge, however, do not refer to the internal forces within the surface, but to the local coordinate system of the line hinge.

So, if you want to transfer nothing else but the axial forces into the shear wall, do not define a hinge for the direction uz. All other hinge directions are to be set as hinged.
