Solution:

Assign sizes in RAM Modeler, RAM Frame, or Gravity Design Modules.

Zero Mass Detected at Story: label.

Solution:

Enter a nonzero mass value in Loads - Masses.

Some mass has been detected on one or more stories that is not associated with any diaphragms. It will be ignored in Analysis unless it is combined with one or more diaphragms. See the Loads - Masses command.

Solution:

The program detected and calculated masses which are not associated with any rigid diaphragm. They are usually from point or line loads stayed outside of any rigid diaphragms and they have mass components defined, or they are from some member self masses, which are not connected t any rigid diaphragms. In Diaphragm Mass dialog, they are labeled as None and they correspond to stories. It is the user responsibility to lump them to any other rigid diaphragm if they are required to be considered in analysis.

Diaphragm # on Story "#" Contains No Lateral Member. This Diaphragm is Exposed to Wind Pressures. Calculated Loads Are Ignored During Analysis.

Solution:

A diaphragm with no lateral member found but it is still exposed to wind. The program calculates wind forces for this diaphragm but it does not apply it to the diaphragm.

Diaphragm # on Story "#"  Contains No Lateral Member. This Diaphragm Contain Mass. The Diaphragm Mass is Ignored if It is Not Combined to Another Diaphragm.

Solution:

A diaphragm with no lateral member found but it still has mass. The program calculates seismic forces for this diaphragm but it does not apply it to the diaphragm. The mass at the diaphragm should be lumped to another diaphragm if it is required to be considered in analysis.

Incorrect Mass Combination Found for Story "#" at Diaphragm "#". Diaphragm Combination Flag is Reset for this Diaphragm.

Solution:

The program detected that there is illegal diaphragm lumping (for example, if mass in Diaphragm A is lumped to Diaphragm B, and if Diaphragm B is later deleted in the Modeler, the program generates this message). Diaphragm lumping flags are reset for such diaphragms, and the user should re-set them.
