Design a 15-ft (4.5-m) cantilever beam of uniform depth to carry a uniform dead load of 0.88 K/ft (12 kN/m) and a live load of 1.1 K/ft (15 kN/m). Assume a beam width b=14 in. (350 mm), f′c = 4 ksi(30 MPa), and fy =60 ksi (400 MPa).
2. A 10-ft (3-m) cantilever beam carries a uniform dead load of 1.50 K/ft (20 kN/m) (including its own weight) and a live load of 0.77 K/ft (10 kN/m) (Fig. 4.16). Design the beam using a variable depth. Draw all details of the beam and reinforcement. Given: f′c = 3 ksi(20 MPa), fy =40 ksi (300 MPa), and b=12 in. (300 mm). Assume h at the free end is 10 in. (250 mm).
