Hi,
Two models set up in the exact way, with the exception of one being a bare RC frame whilst the other includes infill.
The infill wall gives values of 0 of nodal displacement in the x direction whilst carrying out Eigenvalue analysis for the fundamental mode.
Any clarification in relation to this issue would be greatly appreciated.
Cheers

Re: Eigenvalue analysis giving Zero values + nodal displacme
Without more details, it is only possible to offer up a conjecture. Is it possible that, with the in fills added, the fundamental mode is now entirely a y - direction displacement of the structure? Best of luck.
