Seismic Design Forces

Use the building described in Gupta, Problem $5\mathrm{.}11($Figure P$5\mathrm{.}2).$

The total weights at each floor level are: $W_1=820$kips,$W_2=1360$kips, and $W_{\text{r}\text{o}\text{o}\text{f}}=$

$370$ kips.

$($You DO NOT need to calculate weights from the loads provided in the problem

statement.$)$

$($a$)$ Calculate the total inelastic design base shear, $V.$

$($b$)$ Distribute $V$ to each floor level, $F_x.$

$($c$)$ Calculate the horizontal seismic force at each floor level, $E_{\text{h}\text{o}\text{r}\text{i}\text{z}\text{o}\text{n}\text{t}\text{a}\text{l}}.$

$($d$)$ Calculate the total vertical seismic force, $E_{\text{v}\text{e}\text{r}\text{t}\text{i}\text{c}\text{a}\text{l}}.$
