I have a structure with a masonry level on top of 2 levels of cast in place concrete. I have created ELF, ASCE 7-16 response spectra, and Eigen Value load cases and scaled the response spectra per ASCE 7-16. I am finding that when I look at the building story shear report for the response spectra cases the total story shear and change is story shear values are not in agreement. The report is showing that the total shear increases by about 1000 kips from level 3 to level 2, but the report shows a change in shear of nearly 1500 kips (see example snip from report below). The total story shear for the bottom level matches my ELF base shear, so it seems the total shear values are correct. How can I be sure the correct loading has been applied to my members? Has anyone run into this issue before?
