$3\mathrm{.}18$ Given: The plan and section of the building in Fiqure $3.$E$.$ Roof dead load D $=15$ psf$,$

floor dead load D $=20$ psf $($includes an allowance for interior walls$),$ exterior wall dead load D $=$

$53$ ps$.$ Basic wind speed $=105mph.$ Exposure $C$ and ASCE $7$ are specified. The building has a

bearing wall system, braced with special reinforced masonry sheapwalls, The building is

located in Sacramento, California with a mapped short$-$period spectral acceleration of

$0\mathrm{.}56g$ and a mapped one$-$second spectral acceleration of $0\mathrm{.}22g.$ Site Class B$,$ Risk Category IV

should be assumed.
