A wall footing has the following conditions. Determine the minimum width of the footing.The bottom of the footing is at a depth of 3 ft below grade.The service dead load is 13 kips/ft, and the service live load is 7 kips/ft.The wall is 14 in. thick.The footing is 16 in. thick.The allowable soil pressure, qa, is 6,000 psf.The soil has a density of 115 lb/ft3.The concrete has a density of 150 lb/ft3.The concrete cover has a thickness of 3 in.f’c = 3,900 psi and fy = 60,000 psi.

Because the designer has little control over the arrangement of the bars in a circular column, the interaction diagram should be computed for the least favorable bar orientation.

When designing columns, it is often more desirable to use symmetrical reinforcement.

Following the last week of class on-snow, a written final exam will be given the following week outside of class time in which of the following ways?

A rectangular beam has a cross section of b = 14 in., h = 24 in., and d = 21.5 in. It is reinforced with five No. 7 Grade 60 bars. The concrete strength is 4,900 psi (normal weight). The beam has Grade 60 No. 3 stirrups. Determine the transformed cross-sectional area of the bars, Ast.

Determine the maximum axial strength φPn,max for the following tied column.Column width, b = 24 in.Column thickness, h = 18 in.Number of longitudinal bars = 14Size of longitudinal bars = No. 8Size of ties = No. 3Concrete strength = 9,000 psiYield strength of longitudinal bars = 60,000 psiYield strength of ties = 60,000 psi

ACI 318-14 Section 25.7.2.1 specifies that ties shall consist of a closed loop of deformed bar.

Determine the bar-spacing factor, cb, for a simply supported rectangular beam with b = 18 in. and No. 3 stirrups. This beam has five No. 8 bars as longitudinal reinforcement. The clear cover is 1.5 in.
