(a) A two-story hospital facility shown in Figure P2.18 is being designed in New York with a basic wind speed of \(90 \mathrm{mi} / \mathrm{h}\) and wind exposure \(D\). The importance factor \(I\) is 1.15 and \(K_{z}=1.0\). Use the simplified procedure to determine the design wind load, base shear, and building overturning moment.

(b) Use the equivalent lateral force procedure to determine the seismic base shear and overturning moment. The facility, with an average weight of \(90 \mathrm{lb} / \mathrm{ft}^{2}\) for both the floor and roof, is to be designed for

the following seismic factors: \(S_{D S}=0.27 \mathrm{~g}\) and \(S_{D 1}=0.06 \mathrm{~g}\); reinforced concrete frames with an \(R\) value of 8 are to be used. The importance factor \(I\) is 1.5.

(c) Do wind forces or seismic forces govern the strength design of the building?
