An RC (f'c=21 MPa) rectangular beam has a width of 260mm and an overall depth of 470mm. The concrete clear cover is 40mm, the stirrup size is 10mm, and the size of the longitudinal reinforcement is 20mm. Steel yield strength for both the flexure and shear bars is 415MPa. Determine the design shear strength (kN) of the section if the spacing of the shear reinforcement is 50mm.

5. The beam shown is reinforced for positive moment with three epoxy-coated #11 bars. The bars terminate at the center of the supports. Neglecting beam weight (concentrated loads are very heavy), determine if the required development length is satisfied. Assume As required = 4.55in², 2 in. clear cover on all sides of the longitudinal reinforcement, normal weight concrete, #3 stirrups @12 in o.c., f'c = 5000 psi and fy = 60,000 psi. 8 ft | Pu 20 ft Pu 8 ft ge2 of 56 30 in b=14in. ed 5/15/2020 As = 3-#11

QUESTION 1A concrete floor slab measuring 6 m x 3 m is simply supported on one side brick load-bearing walls along the 6 m sides. The concrete slab is 200 mm thick and reinforced at the bottom as follows. a. Main reinforcement (short span i.e the bars are parallel to the short span), Y12, shape code 34 @ 125 mm centre to centre,b. Distribution reinforcement (long-span i.e the bars are parallel to the long span), Y 10, shape code 20 @ 300 mm centre to centre,c. Concrete cover, 30mm,d. Concrete strength, 40MPa. Draw the reinforcement layout for this slab, in plan and section, indicating all thereinforcement and necessary information required by the contractor. Calculate and indicate the number of bars required on your drawing. You do not need to calculate the bar lengths and the curtailment. Neat drawing please
