5 Assume W = 40 ft and D = 40 ft. The unreduced roof live load is 20 psf. The live load on the second and third floors is 65 psf, and the live load on the fourth floor is 40 psf. Compute the total live load in the following columns; Al between third and fourth floor, D2 between second and third floor, and E2 between ground and second floor. (Ans: PAI = 16.4 k, PD2 86.4 k, PE2 = 64.4 k)

SITUATION A: The floor system shown has the following applied loads. Super Imposed Dead Load = 2.00 kPa Live Load = 1.90 kPa Slab Thickness = 100.00 mm Weight of Concrete = 24 kN/m3 Self-Weight of the beam = 1.92 kN/m Material Specifications: f’c = 21.00 MPa fy = 345.00 MPa Steel Cover = 50.00 mm   What is the maximum positive moment of beam BE, acting on the midspan? in kN-m What is the maximum steel ratio of the section located at the supports? What is the actual steel ratio of the beam section at the supports? What is the ultimate moment capacity of the beam at the supports? in kN-m What is the effective flange width at the midspan? in mm What is the height of the compression block of the section at midspan? in mm What is the ultimate moment capacity of the beam at the midspan? in kN-m What would be the height of the CHB that can be placed on beam BE? Assuming the weight of the blocks is 2.30 kN/m per meter height? in meters

Design the simply supported one-way reinforced concrete slab as shown. The service live load is 300 psf and the dead load is the self-weight of the slab only. Use f′c=3000 psi and fy = 60,000 psi. Sketch your design.

span of Gm. 3. Using the RULE OF THUMB", find the initial size of the beam with a simple 4.5m R1 R2 span of 4.5 m. Conct
