Example $5\mathrm{.}1$

A new residential building will be constructed near $$K$$ Atak$$y Campus.

a$)$ Obtain the Seismic Risk Report for the given building considering the following information:

Soil grade: $ZD$

Earthquake Ground Motion Level: DD$-2$

Building Height: $H_N=32m$

b$)$ Plot the horizontal elastic design spectrum in Excel.

c$)$ If building's dominant vibration periods in $x$ and $Y$ directions are $Tx=0\mathrm{.}65sec$ and $Ty=0\mathrm{.}48sec,$

find the horizontal elastic design spectral accelerations.

d$)$ From TSC$-2018,$ obtain the Building's Occupancy Class $($BKS$),$ Importance Factor $($I$),$ Seismic

Design Class $($DTS$),$ Building Height Class $($BYS$),$ Performance Target, and Evaluation$/$Design

Approach.

$T_A=0\mathrm{.}2\frac{S_{D1}}{S_{DS}}$;$,T_B=\frac{S_{D1}}{S_{DS}},$

$S_{ae}(T)=(0\mathrm{.}4+0\mathrm{.}6\frac{T}{T_A})S_{DS},(0T{T}_A)$

$S_{ae}(T)=S_{DS},(T_{B}T{T}_L)$

$S_{ae}(T)=\frac{S_{D1}}{T},(T_{L}T)$
