A reinforced concrete beam has the following properties: Use 2001 NSCP Beam width=320 mm, effective depth, d= 640 mm, concrete strength, fc= 25 MPa, reinforcing steel, fy= 400 MPa, reinforcing steel modulus, Es, = 200,000 MPa, Service dead load moment =350 KN-m. Justify with illustration. a) If the beam is to be designed for a balanced condition, find the required area of steel reinforcement, design balanced moment, and the corresponding service live load moment. b) Find the maximum steel area, the maximum design moment, and the corresponding service live load moment if the beam is to be designed as single reinforced Answers: a) Asb =5,549 mm, oMbn= 952.44 KN-m, ML. = 272 k-m b) As max =4,162 mm, oMn max=775.46, ML = 168 KN-m Repeat using the 2010 NSCP. Justify with illustration Answers: a) Asb= 5,549 mm, oMbn = 687.87 KN-m, ML = 167.42 kN-m b) As max =3,963 mm2, oMn max= 677.7, Mt = 161 kN-m
