,Q1. A Type III-B building has an open parking garage at the first story and R-2
occupancies above. The garage is 60 ft deep and 200 ft wide. What is the maximum
allowable area for the parking garage per CBC Table 503, considering the open
parking garage provisions of Section 406.5?
A. 12,000 sq ft
B. 20,000 sq ft
C. 24,000 sq ft
D. Unlimited
Correct Answer: D. Unlimited
Rationale: Per CBC Section 406.5, open parking garages are not subject to the area limits
of Table 503 when they comply with specific open-front and ventilation requirements. The
provided dimensions and construction type meet the criteria, thus the area is unlimited.
Why Wrong:
A - This is the tabular area for a Type III-B building without considering the open
parking garage exception.
B - This might be the area after applying a frontage increase, but the open parking
garage exception overrides tabular limits.
C - This is a miscalculation applying the wrong factor.
Reference: California Building Code (2022), Sections 406.5, 503, Table 503
Q2. A project uses a structural steel moment frame in Seismic Design Category D.
The steel has a specified minimum yield strength Fy = 50 ksi. According to AISC 341
and CBC Chapter 22, what is the maximum permitted yield-to-tensile strength ratio
for the steel in the protected zones?
A. 0.85
B. 0.90
C. 0.95
D. 1.00
Correct Answer: A. 0.85
Rationale: AISC 341 requires that for SMF and IMF systems, the yield-to-tensile strength
ratio (Fy/Fu) of steel in protected zones must not exceed 0.85 to ensure adequate ductility.
This is a mandatory requirement for seismic force-resisting systems in SDC D.
Why Wrong:
B - This is the limit for some other structural members, but not for protected zones of
seismic frames.
C - This value is allowed for certain non-seismic applications.
D - This is not permitted for any seismic system.
Reference: AISC 341-16, Section A3.1; CBC Chapter 22

, Q3. A covered multi-story parking garage is being designed with a vehicle barrier
system on the roof. The roof is accessible only for maintenance. Per CBC Section
406.4.2 and Section 1607.8, what is the minimum required design load for the vehicle
barrier?
A. A 6,000-lb concentrated load applied at any point
B. A 3,000-lb concentrated load applied at any point
C. A 150 lb/ft horizontal load applied at the top of the barrier
D. A 50 lb/ft horizontal load applied at the top of the barrier
Correct Answer: A. A 6,000-lb concentrated load applied at any point
Rationale: CBC Section 1607.8 requires vehicle barriers to be designed for a
concentrated load of 6,000 lb applied at any point along the barrier for parking garages.
This load is intended to resist vehicle impact, even on roofs accessible only for
maintenance.
Why Wrong:
B - This is the load for passenger car barriers in some older codes, but not current
CBC.
C - This is a generic railing load, not vehicle impact.
D - This is a lower load for pedestrian railings.
Reference: California Building Code (2022), Sections 406.4.2, 1607.8
Q4. A building permit application includes a site plan showing an accessible route
from the public sidewalk to the main entrance. The route crosses a vehicular way with
no curb ramps at the sidewalk. Per CBC Chapter 11B, which of the following is the
most appropriate corrective action?
A. Provide a curb ramp with a running slope of 1:12 maximum and a counter slope of
1:10 maximum.
B. Provide a curb ramp with a running slope of 1:10 maximum and a counter slope of
1:12 maximum.
C. Provide a curb ramp with a running slope of 1:12 maximum and a counter slope of
1:12 maximum.
D. Provide a curb ramp with a running slope of 1:8 maximum and a counter slope of
1:8 maximum.
Correct Answer: C. Provide a curb ramp with a running slope of 1:12 maximum and
a counter slope of 1:12 maximum.
Rationale: CBC Section 11B-406 requires curb ramps to have a running slope of 1:12
maximum and a counter slope of 1:12 maximum to ensure safe transition. This is
consistent with ADA Standards.
Why Wrong:
A - The counter slope is too steep; 1:10 exceeds the maximum.
