I am assigning a mass (kN/m2) as reference load to plates in STAAD model for facade structure. The plates with assigned mass represent the cladding components for seismic analysis.
However, I am receiving this note in STAAD output (as shown below). Generally, what does this (note) mean? Thank you.
*** NOTE: MASS MODEL FORMED WILL BE USED IN SEISMIC/RESPONSE/TIME HISTORY LOADING, IF ANY.
IF MASS MODEL IS SEPARATELY PROVIDED IN INDIVIDUAL LOADING, THE GENERATED MASS
WILL BE REPLACED BY THE MASS PROVIDED IN INDIVIDUAL LOADING.
