Which foundation type is used when soil bearing capacity is insufficient and loads must be transferred to deeper, stronger strata?
Answer: Pile foundation
Pile foundations transfer building loads through weak surface soils down to competent bearing material or rock.
What structural phenomenon occurs when a slender column fails by sudden sideways buckling before reaching material strength?
Answer: Euler buckling
Euler buckling is the elastic instability failure of slender columns where lateral deflection occurs before the material yields.
In a moment-resisting frame, lateral loads are resisted primarily through:
Answer: Rigid beam-to-column connections
Moment frames resist lateral forces through rigid connections that develop bending moments at beam-column joints.
What is the function of rebar in reinforced concrete?
Answer: Resist tensile stresses concrete cannot handle
Steel reinforcement carries tensile forces in zones where concrete, being weak in tension, would otherwise crack and fail.
Which of the following is NOT a type of live load?
Answer: Self-weight of the concrete slab
The self-weight of a structural element is a dead load because it is permanent and does not change with occupancy.
The stiffness of a structural element is best described as:
Answer: Its resistance to deformation under load
Stiffness quantifies how much a member resists deflection or deformation when a force is applied.
