Question 1

What is a shear wall and what forces does it resist?

Accepted Answer

A vertical structural panel that resists lateral (horizontal) forces in its plane

Answer

Shear walls act as vertical cantilever beams to resist in-plane lateral forces from wind and seismic events, transferring them to the foundation.

Question 2

What is the purpose of rebar stirrups in a reinforced concrete beam?

Accepted Answer

To resist diagonal shear stresses and confine longitudinal reinforcement

Answer

Stirrups are closed loops of smaller diameter steel placed perpendicular to the beam span to resist diagonal tension cracking caused by shear forces.

Question 3

What is the concept of tributary area in structural load calculations?

Accepted Answer

The floor area whose load is supported by a particular structural member

Answer

Tributary area is the portion of floor or roof area assigned to each beam or column for load calculation purposes, based on the halfway point between adjacent members.

Question 4

What type of loading causes a beam to twist about its longitudinal axis?

Accepted Answer

Torsional loading

Answer

Torsion occurs when loads are applied off the beam's shear center, causing the member to twist and inducing shear stresses that must be resisted by the cross-section.

Question 5

What is the purpose of expansion joints in a large building structure?

Accepted Answer

To allow thermal expansion and contraction without inducing stresses

Answer

Expansion joints break the structure into independent segments that can expand and contract freely with temperature changes, preventing thermal stresses that could crack structural elements.
