A concrete cube is subjected to biaxial loading. Estimate the compressive strength σ2 if σ1 = 0.2 times the compressive strength, in compression.

High-strength concrete is less economical for many applications. The most effective use of high-strength concrete of the following choices is in _______.

Reinforced concrete structures generally develop cracks. This prevents the reinforcement from functioning effectively.

Floor vibration is a common problem in concrete buildings.

Concrete and reinforced concrete are used all over the globe due to the relatively complex skills required in concrete construction, the economy of concrete construction compared to other forms of construction, and the wide availability of reinforcing bars, aggregate, water and cement.

Beams should be narrower than the columns they sit on.

An engineer will generally provide the over-all building layout, while architects will design individual systems within the building.

When considering the potential loss of life due to a structural failure, a higher factor of safety may be more desirable for an auditorium than for a storage building.

Given that dead load = 51 kips, live load = 22 kips, rain load = 4 kips, and wind load = 12 kips, choose the equation that represents the largest factored load.

In regard to live-load reductions, the average maximum lifetime load _______ as the loaded area increases.
