Page 2 Question 1: A rectangular concrete beam shown in Figure Q1 with fc' = 34 MPa and a bending moment of 75 kN.m. Design the beam so that it will not crack before reaching the bending moments. Hint: All dimensions in mm 400 450 4028 300 Figure Q1 Ans.: Cracking Moment and compare it with Bending Moment: = 70.47 x 10N.mm = 70.47kN.m bending moment of 75 kN.m is less than Cracking Moment 70.47 kN.m Thus the section will cracked by present acting load.
