Can you do #2 please

1. For the beam section presented here below, calculate the reduced nominal moment capacity O M and corresponding ultimate curvature 0u. The beam section is made of concrete with a compressive strength, fe 4,000 psi and reinforcement with a yield strength of fy 60 ksi. The beam has 4 No. 9 bars in tension side and the following number of bars are provided at the compression side of the beam section: 15 (a) A, (b) 2#6 (c) 2#8 (d) 4#9 0, no compression rebar 2.5 4#9 1. 11. 111. Plot ø Mt (vertical axis) vs. reinforcement ratio ρ =-(horizontal axis) in the same graph. Plot øu (vertical axis) vs. rei Plot Eg (vertical axis) vs. reinforcement ratio ρ -(horizontal axis) in the same graph. b d b d b d nforcement ratio ρ (horizontal axis) in the same graph. Comment on the results observed. You may use a spreadsheet but provide hand calculation for case (b) Calculate the reduced nominal negative moment capacity 0 Mt for the rectangular reinforced concrete beam with 4 #8 at the top and 4#9 at the bottom. 2.
