mass participation and missing mass in time history analysis - 02/25/17 02:27 PM

I am doing first time time history analysis using Caesar II. I have following queries:

1.where can I find % mass participation for total modes.

2. I have unusually high vertical loads on +Y supports even though I don't have vertical transients. What can be the reason?

One more item 3.0: The output shows -ve load on +Y support. Should I consider the same load in +ve direction also?
