Load combinations are presented in companion action format.

According to the textbook, calculator errors are one of the three most common sources of error in structural design.

Although concrete’s components are brittle, its stress-strain curve is nonlinear. Which of the following causes this?

Creep deformation in a concrete structure is due to permanent loads and the long duration portion of the variable loads.

According to the textbook, incorrectly looking up or writing down numbers is one of the three most common sources of error in structural design.

Strength limit states involve structural collapse, whereas serviceability limit states involve disruption of the functional use of the structure but not collapse.

Strength limit states involve disruption of the functional use of the structure, whereas serviceability limit states involve structural collapse.

Given that dead load = 45 psf, live load = 100 psf, roof live load = 20 psf, snow load = 35 psf, and wind load = 5 psf, determine the largest factored load.

Which type of aggregate will result in a higher concrete strength?

In some structures, yielding or failure of one member causes a redistribution of load to adjacent members. In other structures, failure of one member can result in complete collapse and therefore would require a lower factor of safety.
