How to remove warning *** WARNING *** DYNAMIC MASSES IN GLOBAL X, Y AND Z DIRECTIONS ARE NOT SAME. WARNING MESSAGES ARE WRITTEN IN _MASSEURO.TXT FILE.

This message indicates that the dynamic mass along the three direction are not same. can you please send us your Staad model?

I am attaching one sample with this warning

Structure Calculations.std

if you look at the input file 

I have assigned inertial masses equally in all directions but still getting the same warning.

Any solution

Waiting for your reply.

Yes, although the inertial mass assigned symmetrically in all direction, program reports the unequal mass distributions. This seems to be a related to a known issue on Response Spectrum definition per Euro in Staad. The similar anomaly was noticed previously in few other models sent by other clients.

It means its a software issue and
Nothing wrong with my STAAD file.
Thank you for your prompt reply.
