Question: PROBLEM 3 . A rectangular beam has b = 3 2 0 m m and d = 4 8 0 m m . The beam

PROBLEM 3.
A rectangular beam has b=320mm and d=480mm. The beam will be designed to carry a service dead load of 200KN-m and
service live load of 150KN-m. Compression reinforcement if necessary, will have its centroid 70 mm from extreme concrete fiber.
Determine the required steel area. Use f'C=28MPa and fy =415MPa.
