2. A3-storey reinforced concrete frame structure with design conditions: site class I, precautionary seismic intensity 8, design basic acceleration of ground motion 0.3g, design group 1, basic natural frequency T1 = 0.6332 s, damping ratio 0.05. The representative gravity loads of each floor and the lateral stiffness of each story are shown. Please: 1) Determine the shear force in each story under frequent earthquake using the base shear method. 2) Calculate the interstory drift and check whether it meets the design requirement of the code.

For the Casper hospital, the weight of each floor is 2500 kips while the roof weighs 2700 kips. The braced frames shown in the Typical Braced Frames Showing Story Height document constitute the dual steel concentrically braced frame for the hospital and allow the Response Modification Coefficient (R) to be 7. The hospital site is classified as Site ClassD for seismic design. T† can be found in ASCE 7-16 Figure 22-14. Calculate the Seismic Base Shear (V) and the lateral equivalent static seismic force (Fr) applied at each story and the roof. Use the ASCE 7-16 document to determine Sps, Ta, Ct, x and I, when doing your calculations. Note that the values in ASCE 7-16 Figure 22-1 need to be divided by 100 to convert from percent to decimal. Alternatively, you can use the Applied Technology Council's Hazards by Location website (https://hazards.atcouncil.org/) but you must still show the calculations by hand. You may use a spread sheet to calculate the force on each floor as the…
