a. Explain the effects of frame stiffness on the shear force and bending moment of shear wall using qualitative SFD and BMD. b. A three storied shear wall is subjected to factored wind force as shown in Fig. 4. The dimensions of the shear wall are also given in the figure. Design the shear wall reinforcement at first level. f' = 3000 psi fy=60000 psi. Use No. #4 bar to design the horizontal and vertical reinforcement. 40 Kip- 80 Kip 80 Kip- 14' 10' 10' 10' 14 110
