Problem 3. $40. Design a rectangular beam to carry the load show, in addition to its self-weight. Assume normal-weight concrete (150 pcf), f'. = 4,000 psi and fy = 60,000 psi. Sketch the cross-section and indicate the dimensions, and the number, size and location of steel bars. PL = 30 k WD = 3 k/ft 10 ft 10 ft 20 ft

A 300mm x 425 rectangular beam is reinforced for tension only with 4-28mm bars. The beam has a concrete cover of 40mm and a stirrup of 10mm diameter bar. The beam carries a live load and a dead load (without its self-weight). Given that unit weight of concrete is 24kN/ cu.m f'c = 21 MPa and fy = 414 MPa, calculate the additional concentrated live load as shown in the figure.

Given a concrete column that would be required to support loads of Pu=400kips and Mu=50 kip-feet, we will determine the column interaction curve and decide if the column is adequate for this particular application. The column will be a 14”x14” square, tied column with #9 bars at the corners. The center of the reinforcement in each corner is 3” from each of the sides. The f’c of the concrete is 4 ksi and the reinforcement is Grade 60.  Determine if the column is acceptable for this application. Calculate the value of Mu and Pu.

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)
