Problem $2$

The $5-$story building below uses special moment resisting frame $($SMRF$).$ Mapped spectral accelerations for the short period, $\backslash (\backslash$mathrm$\{$Ss$\}=2\mathrm{.}1\backslash$mathrm$\{$~g$\}\backslash ).$ Mapped spectral accelerations for the long period, $\backslash (\backslash$mathrm$\{$S$\}1=0\mathrm{.}95\backslash$mathrm$\{$~g$\}\backslash ).$ Site profile is very dense soil. Building is standard occupancy. Typical floor weight, WF $\backslash (=350\backslash )$ kips, Roof weight, WR $\backslash (=250\backslash )$ kips. Determine $1)$ Seismic base shear, V$.$ Use the IBC Equivalent Lateral Force Method, $2)$ The vertical load distribution Fx$.3)$ The diaphragm forces Fp$.$
