1. Figure 6 shows illustration of one beam. Assume the depth of the beam is 450 mm, the width is 250 mm and the length is 3000 mm. Diameter of the top and bottom bars are 16 and 25 mm, respectively. Diameter of the links is 10 mm with 50 mm spacing centre to centre. Yield strength of main bars and links are 500 MPa and 250 MPa, respectively. Present the beam into 2D drawing including the cross-sectional details for construction drawing. Figure 6 (10 marks)
