How to covert "Load to Masses" in Midas Civil for Self Weight to perform Eigen Value Analysis?

Question:
When performing an Eigenvalue Analysis, if a Load Case that includes the “Self Weight” load is added to the “Loads to Masses”, will the “Self Weight” mass be added to the mass matrix, or does the “Structure Type/Convert Self-weight into Masses” button still needs to be checked?

Answer:

As shown in our online manual, Loads to Masses “does not convert self-weight into masses. In order to convert self-weight into masses, "Converting Type of Model Weight to Masses" in Model>Structure Type can be used.”


Here is the online link for your reference [Home > Start > Load > Static Loads > Loads to Masses].
