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

1/ Calculate maximum deflection of the beams  (This was solve it) 2/ Check the suitability of the section assuming the code limitation of L/240. 3/ If maximum deflection doesn’t meet the code requirement, propose your solution

A rectangular reinforced concrete beam has a length of 14 m is simply supported atboth ends. The width of beam is 350mm and the overall depth is 550  mm. Determine the area of the steel reinforcements if the beam is to carry a DL = 15kN/m and LL =18kN/m. The concrete strength fc = 25  and steel yield fy = 400 ������. Use 60 mm concretecover.
