1. Design a simply supported reinforced concrete beam of 7 m length and subjected to a factored uniformly distributed load of 100 KN/m If required, check for shear f'c = 30 Mpa 80 cm fy = 450 Mpa 30 cm Exercise (2): For the shown cross sections in figures, calculate the ultimate design moment that can be resisted by each section. Given: f= 35 Mpa fy = 450 Mpa 40 25mm 100 KN/m 100 cm 06 7 m 50 22mm Cross-section 50 cm Exercise (3): A rectangular section of width b=30 cm is required to resist an ultimate moment of 300 KN.m Given: f= 30 Mpa fy=450Mpa It is required to: - Design the section
