The PE Civil Structural exam is one of the most demanding professional engineering exams in the United States—and one of the most rewarding to pass. With a first-time pass rate hovering around 58%, it requires serious preparation across multiple design codes, material systems, and analysis methods. This guide provides a complete breakdown of every topic area on the exam, the critical code references you need to master, and a 16-week study timeline that will carry you from day one to exam day with confidence.

Who Should Take the PE Civil Structural Exam?

The PE Civil Structural depth exam is designed for engineers whose practice centers on the analysis and design of structural systems—buildings, bridges, foundations, and other load-bearing structures. If your daily work involves reinforced concrete design, structural steel connections, load calculations per ASCE 7, or foundation engineering, this is your exam. You must hold an FE/EIT credential and have at least four years of qualifying professional experience under a licensed PE before you are eligible to sit for the exam.

The exam consists of 80 questions administered during a 9-hour appointment (approximately 8 hours of testing time plus a 50-minute break). It is computer-based, offered year-round at Pearson VUE centers, and costs $400. The exam is closed-book—the only reference you may use is the NCEES PE Civil Reference Handbook, which is provided electronically on your testing computer.

Complete Topic-by-Topic Breakdown

The PE Civil Structural exam covers eight major knowledge areas. Below is a detailed breakdown of each—including approximate question counts, priority rankings, critical formulas and code references, and targeted study tips.

1. Structural Analysis (~12 questions) — HIGH Priority

Structural analysis is the backbone of this exam. You need to analyze both determinate and indeterminate structures quickly and accurately. Expect problems involving load path identification, internal force calculations, deflection computation, and stability assessment.

Key subtopics:

Critical formulas: Virtual work: 1 * delta = integral(m * M / EI)dx. Moment distribution carry-over factor = 0.5 for prismatic members. Degree of indeterminacy = reactions + members + 3*closed loops - 2*joints (for trusses) or 3*members + reactions - 3*joints - conditions (for frames).

Study tip: Master moment distribution first—it appears frequently and is efficient for continuous beams and simple frames. Practice drawing shear and moment diagrams from memory until you can produce them in under two minutes for common loading cases. Do not skip influence lines; they are a reliable source of questions and connect directly to moving load problems.

2. Loadings (~10 questions) — HIGH Priority

Load determination drives every structural design problem. This section tests your ability to calculate design loads from ASCE 7 and to combine them using the correct load combination framework.

Key subtopics:

Critical code reference: ASCE 7-22, Chapters 2 (Combinations), 4 (Dead/Live), 26–30 (Wind), 7 (Snow), 8 (Rain).

Study tip: Memorize the LRFD load combinations—they appear in nearly every design problem on the exam. For wind loads, understand the step-by-step procedure for calculating design wind pressure: determine risk category, find basic wind speed V, compute velocity pressure exposure coefficients Kz, then assemble the pressure equation. Practice snow load calculations with drift provisions, as these multi-step problems are common.

3. Reinforced Concrete (~14 questions) — HIGH Priority

Reinforced concrete is tied for the highest question count on the exam. You must be fluent in ACI 318 provisions for flexure, shear, development length, and column design.

Key subtopics:

Critical code reference: ACI 318-19, especially Chapters 6 (Analysis), 9 (Beams), 10 (One-Way Slabs), 8 (Two-Way Slabs), 10 (Columns), 22 (Sectional Strength), 25 (Reinforcement Details).

Study tip: The flexural design equation Mu = phi * As * fy * (d - a/2) is the single most important formula for this section. Practice solving for the required steel area As given a factored moment, and practice verifying that the section is tension-controlled (net tensile strain ≥ 0.005). For shear, always check whether the concrete contribution Vc alone is sufficient before sizing stirrups. Interaction diagrams for columns are almost guaranteed to appear—practice reading them to find phi*Pn and phi*Mn for a given eccentricity.

4. Structural Steel (~14 questions) — HIGH Priority

Structural steel shares the top spot with concrete. AISC 360 governs nearly every steel question, and you must be comfortable with both LRFD and ASD approaches.

Key subtopics:

Critical code reference: AISC 360-16 (Specification), AISC Steel Construction Manual 15th Edition (Tables for available strength, dimensions, Zx, Sx, section properties).

Study tip: Know the AISC Manual table layout cold. The most efficient way to solve steel design problems during the exam is to use the available strength tables directly rather than computing Fcr or Mn from first principles. Practice the beam-column interaction check (H1-1a and H1-1b) until it is automatic—these problems appear on virtually every administration. For connections, focus on bolt group strength and fillet weld capacity; always check all applicable limit states (shear, bearing, tearout, block shear).

5. Wood Design (~8 questions) — MEDIUM Priority

Wood design follows the National Design Specification (NDS), which uses a system of adjustment factors applied to reference design values. The adjustment factor framework is unique to wood and requires dedicated study.

Key subtopics:

Critical code reference: NDS 2018, NDS Supplement (reference design values), SDPWS (Special Design Provisions for Wind and Seismic).

Study tip: The most common mistake on wood problems is forgetting an adjustment factor. Develop a checklist for each design type (flexure, compression, connections) and apply it systematically. The column stability factor Cp is the most calculation-intensive adjustment factor—practice deriving it from FcE and Fc* until the procedure is comfortable. For connections, the NCEES reference handbook typically provides yield limit equations; focus on identifying which yield mode governs.

6. Masonry (~6 questions) — MEDIUM Priority

Masonry design follows TMS 402 (formerly ACI 530). While it carries fewer questions than concrete or steel, the questions can be straightforward if you understand the design philosophy.

Key subtopics:

Critical code reference: TMS 402 (Building Code Requirements for Masonry Structures).

Study tip: Many candidates neglect masonry because it carries only six questions, but those six questions can make the difference between passing and failing. The design approach for reinforced masonry flexure closely mirrors reinforced concrete—if you are strong in ACI 318, you can learn masonry flexure quickly. Pay attention to the distinction between grouted and ungrouted sections, as this affects both the effective area and the shear capacity. Practice at least 10–15 masonry problems before exam day.

7. Foundations (~8 questions) — MEDIUM Priority

Foundation design bridges structural engineering and geotechnical engineering. You need to size shallow and deep foundations, check stability of retaining walls, and compute lateral earth pressures.

Key subtopics:

Critical formulas: Ka = tan^2(45 - phi/2), Kp = tan^2(45 + phi/2), K0 = 1 - sin(phi). Terzaghi: qu = c*Nc + q*Nq + 0.5*gamma*B*N_gamma.

Study tip: Retaining wall stability checks (overturning, sliding, bearing) follow a repeatable procedure that becomes reliable once you practice it five or six times. For shallow foundations, make sure you can distinguish between gross and net bearing capacity, and know when to apply shape factors. The structural design of footings—computing one-way shear, punching shear, and required flexural reinforcement—ties directly back to your ACI 318 knowledge, so study these topics together.

8. Seismic Design (~8 questions) — MEDIUM Priority

Seismic design questions draw from ASCE 7 Chapters 11 through 22. The exam tests your ability to determine seismic design parameters, compute base shear, and apply detailing requirements for different seismic design categories.

Key subtopics:

Critical code reference: ASCE 7-22, Chapters 11 (Definitions and Parameters), 12 (Seismic Design Requirements for Building Structures), 13 (Nonstructural Components), and Tables 12.2-1 (Design Coefficients R, Cd, omega_0), 12.12-1 (Allowable Story Drift).

Study tip: The equivalent lateral force (ELF) procedure is a step-by-step process, and the exam will test multiple steps within a single problem. Practice the full sequence: determine SDS and SD1, find the seismic design category, select R and Ie, compute Cs, calculate base shear V, then distribute it vertically. Know the irregularity definitions—the exam frequently asks you to identify whether a given building has a specific irregularity. The diaphragm force equation Fpx is a common standalone question; practice computing it for multi-story buildings.

LRFD vs. ASD: When Each Applies

The PE Civil Structural exam requires familiarity with both Load and Resistance Factor Design (LRFD) and Allowable Stress Design (ASD). Understanding when each applies is essential.

When a problem does not explicitly state which method to use, look at the loads given. If they are factored (e.g., “Mu = 250 ft-kips”), you are working in LRFD. If they are service-level (e.g., “M = 250 ft-kips due to D + L”), you are likely in ASD territory.

Recommended 16-Week Study Timeline

Most candidates who pass the PE Structural exam invest 300–500 hours of focused study. Here is a 16-week plan that allocates time proportionally to question weight and difficulty.
