(a) A two-story hospital facility shown in
Figure P2.18 is being designed in New York with a basic
wind speed of 90 mi/h and wind exposure D. The impor-
tance factor I is 1.15 and Kz = 1.0. Use the simplified pro-
cedure 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 lb/ft2
for both the floor and roof, is to be designed for the following seismic factors: SDS = 0.27g and SD1 = 0.06g;
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?
