Answer the dynamic response question below for the three-story shear building above for Design PGA = 0.4g. The damping ratio for all modes is assumed to be 5%. (Use the attached 84.1th percentile spectrum.)

$\underline{S}_{n}=\Gamma _{n}\underline{m}\underline{\phi}_{n}$

$\Gamma _{n}= \frac{L_{n}}{M_{n}}$
