INTRODUCTION
The NCEES PE Civil Structural Exam is a comprehensive assessment designed to evaluate the competency of
engineers seeking professional licensure. This exam focuses on the technical proficiency required to ensure the
safety, stability, and durability of structural systems within the built environment. It assesses a candidate’s ability to
apply advanced engineering principles, interpret building codes, and solve complex real-world problems. The
assessment utilizes a multiple-choice format, incorporating scenario-based questions that mirror professional
practice. Emphasis is placed on critical decision-making, regulatory compliance, and the application of
engineering judgment to safeguard public health and welfare through sound structural design and analysis.
,SECTION ONE: QUESTIONS 1–100
1. A reinforced concrete beam is subjected to a factored moment of 250 kip-ft. If the design strength provided
by the reinforcement is 280 kip-ft, what is the primary requirement for the strength reduction factor (ϕ)
according to ACI 318?
A. The factor must be 0.65 for all reinforced sections.
B. The factor is determined by the net tensile strain in the extreme tension steel.
C. The factor is a constant 0.90 regardless of strain.
D. The factor depends solely on the concrete compressive strength.
🟢 B. The factor is determined by the net tensile strain in the extreme tension steel.
🔴 RATIONALE: Per ACI 318, the strength reduction factor for flexure ranges from 0.65 to 0.90 based on whether
the section is compression-controlled, transition, or tension-controlled, which is defined by the net tensile strain (ϵt
).
2. Which of the following best describes the "p-delta" effect in structural analysis?
A. The secondary effect of column axial loads acting upon the lateral displacement of the structure.
B. The primary deflection caused by wind loading on a rigid frame.
C. The settlement of a foundation due to hydrostatic pressure.
D. The thermal expansion of steel members in high-temperature environments.
🟢 A. The secondary effect of column axial loads acting upon the lateral displacement of the structure.
🔴 RATIONALE: P-Delta effects are second-order effects where the vertical load (P) multiplied by the lateral
displacement (delta) creates additional moments that must be accounted for in the structural design.
, 3. Under the NSPE Code of Ethics, what is the engineer's paramount responsibility?
A. To ensure the project remains under budget for the client.
B. To protect the proprietary interests of the employer.
C. To hold paramount the safety, health, and welfare of the public.
D. To provide the most aesthetically pleasing design possible.
🟢 C. To hold paramount the safety, health, and welfare of the public.
🔴 RATIONALE: The Fundamental Canons of the NSPE Code of Ethics state that the safety, health, and welfare
of the public are the highest priority for any licensed professional engineer.
4. When calculating wind loads using ASCE 7, the Gust Effect Factor (G) for a "rigid" structure is typically
taken as:
A. 0.65
B. 0.85
C. 1.00
D. 1.15
🟢 B. 0.85
🔴 RATIONALE: ASCE 7 provides a simplified gust effect factor of 0.85 for rigid structures, which are defined as
having a fundamental natural frequency greater than or equal to 1 Hz.
5. In a bolted connection using high-strength bolts, "snug-tight" condition is defined as:
A. The tightness attained by a few impacts of an impact wrench or the full effort of an ironworker with a spud
wrench.
, B. 50% of the minimum specified bolt tension.
C. Tensioning the bolt until the threads are stripped.
D. The condition where the bolt can still be turned by hand.
🟢 A. The tightness attained by a few impacts of an impact wrench or the full effort of an ironworker with a spud
wrench.
🔴 RATIONALE: The Research Council on Structural Connections (RCSC) defines snug-tight as the tightness
that exists when all plies in a joint are in firm contact, typically achieved by an ironworker's full effort or a few hits
of an impact wrench.
6. For a soil sample, if the Liquid Limit (LL) is 45 and the Plastic Limit (PL) is 20, what is the Plasticity Index
(PI)?
A. 65
B. 2.25
C. 25
D. 15
🟢 C. 25
🔴 RATIONALE: The Plasticity Index is calculated as P I = LL − P L. Therefore, 45 − 20 = 25.
7. In timber design, the adjustment factor CD refers to:
A. Size Factor
B. Wet Service Factor
C. Load Duration Factor
D. Temperature Factor
