ICC System Architecture and Design 4

Question 1

According to the IBC, what is the maximum number of stories permitted for a Group R-2 occupancy building of Type V-A construction with an NFPA 13 sprinkler system?

Accepted Answer

5 stories

Answer

2 stories

Answer

3 stories

Answer

4 stories

Question 2

Under the IBC, the 'area of refuge' concept is primarily associated with which building system design element?

Accepted Answer

Accessible means of egress

Answer

Fire suppression zoning

Answer

Smoke control compartmentalization

Answer

Structural collapse prevention

Question 3

In the ICC framework, what distinguishes a 'fire wall' from a 'fire barrier'?

Accepted Answer

Fire walls provide structural independence and allow buildings on either side to be treated as separate, while fire barriers do not provide structural separation

Answer

Fire walls must extend to the exterior; fire barriers are interior only

Answer

Fire barriers require higher ratings than fire walls

Answer

Fire walls are only required in Group H occupancies

Question 4

Which seismic design category (SDC) triggers the most stringent structural system restrictions under the IBC?

Accepted Answer

SDC F

Answer

SDC A

Answer

SDC C

Answer

SDC D

Question 5

What is the purpose of a 'soft story' irregularity check in building system design?

Accepted Answer

To identify stories where lateral stiffness is significantly less than the story above, creating potential weak points

Answer

To verify that floor-to-floor heights are consistent throughout the building

Answer

To ensure mechanical rooms do not overload structural floors

Answer

To confirm egress stairwells are adequately stiffened

Question 6

Under the IBC, which document primarily governs the design loads (dead, live, wind, snow, seismic) for building structural systems?

Accepted Answer

ASCE 7

Answer

AISC 360

Answer

ACI 318

Answer

NFPA 5000

Question 7

In a building designed with a 'core and shell' structural concept, what role does the central core typically serve?

Accepted Answer

It functions as the primary lateral force-resisting system using shear walls or braced frames

Answer

It houses only mechanical and plumbing systems

Answer

It provides the main gravity load path for perimeter columns

Answer

It serves as a fire-rated egress stairwell only
