Hello, please solve the question about reinforced concrete from the sixth and seventh chapters of the third civil stage
Situation: A beam has a width of 300 mm and total depth of 600 mm strength f'c-36 MPa. Steel yield strength fy=415 MPa The section is to be reinforced for tension only and the effective concrete cover is 65 mm. Which of the following most nearly gives the value of our balanced steel ratio? a. 0.00370 b. 0.03456 C. 0.02860 d. 0.03522 Which of the following most nearly gives the value of our balanced distance of the cuter most fiber of compression fiber to our neutral axis? a. 313.256 mm b. 354.68 mm C. 333.333 mm d. 322.435 mm Which of the following most nearly gives the value of our balanced depth of compression block? a. 248.412 mm b. 266.2676 mm C. 301.478 mm d. 281.261 mm
two span beam subjected to shear and flexure only is reinforced as follows: Section @ midspan @ face supports Top bars 2-20mm 5-20mm Bottom bars 3-20mm 2-20mm Given Stirrup diameter: 10 mm concrete fc = 21 mpa steel rebar fy = 415 mpa stirrup fy = 275 mpa beam size b x h = 270 mm x 450 mm assume all bars laid out in single layer calculate the following: a) tensile steel ratio in positive bending moment at midspan (round off to 5 decimals) b) design moment strength of section at midspan for positive bending ( in kN•m , nearest whole number) c) nominal design strength of section at face of support for negative bending ( in kN•m , nearest whole number)
A simply supported beam is reinforced with 5-p25 mm at the bottom and 2-020 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: Depth of the neutral axis from the extreme concrete compression fiber to the nearest whole number = mm Design strength of the beam section to the nearest whole number = kN -m 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)
A rectangular beam has the dimensions (see Figure) b = 12 in., h - 20 in, and d 17 in. and is reinforced with three No. 9 (No. 29) bars so that As - 3.00 in. The concrete compressive strength fe is 4000 psi, and the tensile strength In bending (modulus of rupture) is 475 psi. The yield point of the steel f, is 60,000 psi. Determine the concrete compression stress at the top fiber caused by a bending moment M- 10 ft-kips. 9- 6.78 in, I= 4067 in, Es= 29000000, E = 3600000 17 in. 20 in. 3 #9 bars (A, - 3.00 in.?) 3 in. -12 in- Select one: a. 390 psi b. 1390 psi c. 200 psi d. 250 psi

Hope your help concrete design CE 410 thanks
Use Code for Structural Concrete (ACI 318-19): i need the answer quickly i need all the steps.
Referenced concrete n=16
GIVEN: A column made of 2 materials: a W 6 x 15 structural steel section Page 3 encased in concrete as shown. Load = 60 kips Esteel = 30 x 10' ksi Econcrete = 3 x 10° ksi I = 29.1 in. k = 29.1 in (Wbx15 FA = 15 in Length = 10 feet REQ'D: A) Load in the concrete and load in the steel section B) Compressive stress in the concrete and compressive stress in the steel section
