ARE Structural Systems and Technology 2

Question 1

Which foundation type is used when soil bearing capacity is insufficient and loads must be transferred to deeper, stronger strata?

Accepted Answer

Pile foundation

Answer

Pile foundations transfer building loads through weak surface soils down to competent bearing material or rock.

Question 2

What structural phenomenon occurs when a slender column fails by sudden sideways buckling before reaching material strength?

Accepted Answer

Euler buckling

Answer

Euler buckling is the elastic instability failure of slender columns where lateral deflection occurs before the material yields.

Question 3

In a moment-resisting frame, lateral loads are resisted primarily through:

Accepted Answer

Rigid beam-to-column connections

Answer

Moment frames resist lateral forces through rigid connections that develop bending moments at beam-column joints.

Question 4

What is the function of rebar in reinforced concrete?

Accepted Answer

Resist tensile stresses concrete cannot handle

Answer

Steel reinforcement carries tensile forces in zones where concrete, being weak in tension, would otherwise crack and fail.

Question 5

Which of the following is NOT a type of live load?

Accepted Answer

Self-weight of the concrete slab

Answer

The self-weight of a structural element is a dead load because it is permanent and does not change with occupancy.
