1. Reduced MI will not be used for calculating fundamental natural frequencies of the structure. Seismic loads are calculated using the above structure frequencies only

Is that so? I can't find tha ...

I wounder how the 0.3*Q was arrived at in the seismic case. I presume the 0.3, was probably the live load reduction, as with IS:1893-2000 (where the reduction was allowed for design load cases too).

In the process, the Vb-dash is, as in earlier ...

I think itís fairly clear:
1.5 DL + 1.5 ELX becomes 1.5 DL + 1.5*(100/80) ELX which is 1.5 DL + 1.875 ELX
1.2 (DL + LL + ELX) becomes 1.2 (DL + LL) + 1.2*(100/80) ELX, which is 1.2 (DL + LL) + 1.5 E ...
