Design the flexural reinforcement for a rectangular section with a width of 10 in. and a total depth, h of 20 in. that is subjected to Mp = 88 k-ft and M₁ = 70 k-ft. fc = 6 ksi and fy = 80 ksi. Draw the detailing.

Subject reinforced concrete design please solve part C and D

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

1. A rectangular beam section is 10 in. wide and has a structural depth of 13.5 in. Reinforcement consists of two No. 8 bars. Given that the strength normalweight concrete is 4000 psi and there is NO shear reinforcement in the section, determine the nominal shear capacity allowed by the ACI Code. (5 pt) (Hint: No web reinforcement, so Vc = 8λ¸λ(pw)¹/³¸ √ Fcbw d cbwd shall be used).

4.3 A simply supported beam is reinforced with 5-ϕ25 mm at the bottom and 2-ϕ20 mm at the top of the beam. Concrete covering to centroid of reinforcement is 70 mm at the top and 64 mm at the bottom of the beam. The beam has a gross depth of 450 mm and gross width of 300 mm. fc’= 28 MPa, fy = 415 MPa.  Assume bars laid out in single layer. Calculate the following if the limiting tensile steel strain is 0.004 for a ductile failure: Calculate: Maximum service uniform live load over the entire span in addition to a DL = 20 kN/m (including the weight of the beam) if it has a span of 6 m =  _____?____  kN/m (to the nearest whole number)
