II. Given: A five-story hospital with no emergency facility has the special moment frames as the seismic force resisting system. The following information is given the hospital building: Building Material - Reinforced Concrete Ss = 1.50 (g); S₁ = 0.60 (g); TL = 8 sec. Site class = C Each story height = 15 feet - Floor area = 20,000 ft² (each level); Roof area = 20,000 ft² Floor weight = 120 psf; Roof weight = 100 psf Exterior wall weight tributary to each floor = 50 kips Grade Grade • Exterior wall weight tributary to roof = 30 kips • Consider interior partition wall weights. Required: 1) The effective seismic weight at each level above the base of building. 2) The seismic base shear of the building 3) The story forces (the seismic lateral force at each level of the building).

Given:
A five-story hospital with no emergency facility has the special moment frames as the seismic force
resisting system. The following information is given the hospital building:
Building Material - Reinforced Concrete
Ss = 1.50 (g); S₁ = 0.60 (g); TL = 8 sec.
Site class = C
Each story height = 15 feet
-
Floor area = 20,000 ft² (each level); Roof area = 20,000 ft²
Floor weight = 120 psf; Roof weight = 100 psf
Exterior wall weight tributary to each floor = 50 kips
Grade
Grade
•
Exterior wall weight tributary to roof = 30 kips
•
Consider interior partition wall weights.
Required:
1) The effective seismic weight at each level above the base of building.
2) The seismic base shear of the building
3) The story forces (the seismic lateral force at each level of the building).
