1. Design a round spiral column to support an axial dead load of 1200 kN andlive load of 1500 kN. Use gross steel ratio of approximately 3%. Assumefc' = 28 MPa and fy = 415 MPa. Use 25 mm bars for mainreinforcement and 10 mm bars for spiral reinforcement. Use NSCP 2015.a. Compute for the required area of steel.b. Determine the number of longitudinal bars.

Design the reinforcement of a rectangular beam to resist a dead load moment of 200kN.m (including its own weight) and a live load moment of 300kN.m. The beam is limited in size to 350mm by 600mm overall depth. Steel covering from centroid of bars to outermost fiber is 100mm for both tension and compression reinforcement. Use fc'=27.5Mpa, fy = 414MPa,20mm barsA. As'= 7 of 20mm and As=14 of 20mmB. As' = 9 of 20mm and As=18 of 20mmC. As'= 5 of 20mm and As=10 of 20mmD. As' = 3 of 20mm and As=6 of 20mm Please provide neat and clear solutions

Design a reinforcement of a doubly reinforced beam if the beam has a size of 425 mm x 600 mm. Use fc = 21MPa , fy = 414MPa
S9. Knowing that the allowable normal stress for the steel used is 150 MPa, select the most economical metric wide-flange beam to support the loading shown in Figure 9.0. 50 kN/m A D B -2.4 m- 0.8 m 0.8 m Figure 9.0 $10. Determine the average shearing stress in the web of the beam indicated and check whether the design obtained earlier for that beam is acceptable, knowing that the allowable shearing stress for the steel used is 110 MPa. Consider the beam of $9 above.
Problems 6 - 7: Design the following sections by finding As and A's. Mu is provided below the figure. Use fy = 60,000 psi, f'c = 4000 psi. Start the design by verifying that compression steel is needed to meet the required strength. Once you have calculated A, and A's, select bar size and # using the tables, then show that the actual resultant steel areas satisfy the design requirements listed below: 14" Use Mu =900k-ft capacity: Mn > Mu/ ductility: &t >= 0.005 (note: it is not required that &'s > 0.00207) minimum steel: As > As,min 3" 23" 3" stut. * 10" 8" 8" Use Mu=300k-ft 3" 14" 3"
