The problem statement states,

Given that be = 34″, f’c = 3.5 ksi, and fy = 60 ksi, calculate the design moment strength of the T-section shown in the figure below per ACI Code 318-11.

The problem statement states,

A series of simply supported concrete beams have a span length of 16 ft and are spaced at 8 ft. They support a 4 in. thick concrete floor slab. The dimensions and beam reinforcement are shown in the figure below.

If f’c = 3 ksi and fy = 60 ksi, calculate the design moment strength of a typical interior beam per ACI 318-11.

The problem statement states,

The rectangular section below has the following properties:

Width = b = 12″

Effective depth = d = 22.5″

Tension reinforcement = (6) no. 9 bars

Compression reinforcement = (3) no. 7 bars

Calculate the design strength of the beam if f’c = 5 ksi and fy = 60 ksi using ACI Code 318-11.

The problem statement states,

The rectangular section below has the following properties:

Width = b = 12″

Effective depth = d = 22.5″

Tension reinforcement = (6) no. 9 bars

Compression reinforcement = (2) no. 6 bars

Calculate the design strength of the beam if f’c = 4 ksi and fy = 50 ksi using ACI Code 318-11.

The problem statement states,

Find the design strength and the location of the neutral axis of the rectangular section shown below using ACI Code 318-11. The reinforcement used is (6) no. 9 bars arranged in two rows.

b = 13 in

d = 23.5 in

h = 27 in

dt = 24.5

f’c = 4 ksi

fy = 60 ksi
