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

Given that dead load = 30 psf, live load = 60 psf, roof live load = 35 psf, snow load = 40 psf, and wind load = 25 psf, determine the largest factored load.

Occupants of concrete buildings commonly complain of floor vibrations.

In structural design, the symbol Lo represents _______.

Strength-reduction factors are _______, while load factors are _______.

The floor and roofing systems are expected to be roughly ________of the structural costs of a cast-in-place building.
