Building Engineering Structural Analysis and Design 2

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

A wall designed only to carry vertical gravity loads

Answer

A partition wall that distributes floor loads to columns

Answer

A retaining wall that resists lateral soil pressure

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

To anchor the beam into column connections

Answer

To prevent thermal cracking from temperature changes

Answer

To resist compressive forces in the beam web

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

The area of a foundation required to support a column

Answer

The effective span of a beam between supports

Answer

The cross-sectional area of a structural member

Question 4

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

Accepted Answer

Torsional loading

Answer

Bending moment

Answer

Shear force

Answer

Axial compression

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

To increase the building's lateral stiffness

Answer

To separate different structural systems

Answer

To provide access for building maintenance

Question 6

What does the term 'ductility' mean in the context of seismic structural design?

Accepted Answer

The ability of a structure to deform inelastically without sudden failure

Answer

The stiffness of a structure under lateral loads

Answer

The maximum elastic deformation before yielding

Answer

The ratio of live load to dead load capacity
