Calculate the nominal moment, Mn for a beam that has b=12.5″, d=28″, As is 4#9, F’c=4,000 psi and Fy=40,000psi.

What is the yield strain of A615 grade 60 steel?

Calculate the weight of a reinforced concrete beam that has a cross section b=12″and h=25″. Span length is 20ft

What does the moment of inertia represent?

Calculate the weight of a reinforced concrete beam that has a cross section b=15″and h=28″. Span length is 25ft

In a simply supported beam, where does the maximum bending moment occur?

What is the ultimate limit state for reinforced concrete beams?

Determine the amount of steel area required for a beam with b=10″, h=18″, f’c=4,000 psi, fy=60,000 psi and Mu=145 k-ft. Choose a size and amount of bars and check for beam width.
