Given: A doubly reinforced rectangular concrete beam is subjected to a factored ultimate moment M,=1396 kN.m. Assume f= 28 MPa, 1 = 420 MPa. Assume d = 75 mm, d= 700 mm, and b= 380 mm. Design the section for this ultimate moment. Consider that pmar "Po 00s = 0.01806 as singly reinforced beam. Keep the draft of your calculations with you; just fill your answers to the questions shown below, and no need to send any attachment. Check the capacity of the section if singly reinforced, and calculate Mamax kN.m What is the required area of tension steel A, (mm) mm What is the required area of compression steel A', (mm)? mm What will be the compression steel (A) condition at ultimate?
