Problem No. 3: A plane frame of a two-story reinforced concrete SMRF (R=8.5) office building is shown in Figure 2. The building is of Occupancy Category IV (1 = 1.0) and is located 5 km away from a fault line of seismic source type C (Na = 1.0; N = 1.0) in zone 4. The soil profile to which the structure is constructed is stiff soil (Sp), with Seismic Coefficient Ca = 0.44 Na and Cv = 0.64 Nv. The total computed dead load per floor on the frame is: W Basement = 500 KN; W Ground Level = 500 KN; W Level 2 = 700 kN: W Level 3 = 1000 KN. a. What is the near most value of the design base shear of the building in N? b. What is the value of the lateral forces in Level 2 and Level 3 in KN? c. By Portal method, determine the bending moment, shear and axial forces in girders and columns. c Level 3 4 m Level 2 ! h 4 m Ground Level a d g Basement 4 m 6 m 6m 6 m Figure 2
