Use the building from Lab $2,$ a $5-$story hospital building located in

downtown St$.$ Louis, MO$,$ and

$$ estimate the seismic weight on each floor and roof from Lab $2$ cals.

$$ determine the spectral response acceleration parameters and draw the

response spectrum for the site assuming site $($soil$)$ is class D$.$

$$ compute the design earthquake loads acting on each floor if the structural

system being proposed is a special steel concentrically braced frame.
