CA Seismic study guide

CA Seismic · Work through your exam, one topic at a time.

The California Civil Seismic Principles Examination is one of the California-specific exams administered by the Board for Professional Engineers, Land Surveyors, and Geologists (BPELSG) for civil engineering licensure in the state. It is intended for civil engineer applicants who must demonstrate knowledge of seismic design principles as part of the California licensing process. The exam is multiple choice and focuses on seismic principles applied to civil engineering practice, including how building code provisions and referenced standards govern seismic analysis and design. Preparation should center on the code editions the Board states are currently tested. According to the Board, the Civil Seismic Principles Exam will continue the test to the 2022 California Building Code and ASCE 7–16 for the remainder of 2026. The Board also announced that the 2025 California Building Code and ASCE 7–22 will be implemented on the 2027 Civil Seismic Principles Exam. Topics on this exam: Seismic Principles. The CA Seismic study guide has 1 section and about 410 words.

Seismic Principles: Ground Motion, Structural Response, and Code-Based Design

The Seismic Principles domain tests whether you can connect ground motion to structural behavior and then to code provisions. Candidates must understand fault geometry and seismic hazard (fault type, distance, site class, and how soft soils amplify long-period shaking), the difference between magnitude (energy released) and intensity (local effects), and the response spectrum concept. Know that a response spectrum plots peak response versus period for a given damping and earthquake, that spectral acceleration generally peaks at short periods and decays at long periods, and that site class shifts and amplifies the spectrum. Understand how period, mass, and stiffness relate (T grows with mass and with height, shrinks with stiffness), why resonance matters, and how ductility and overstrength reduce design forces relative to elastic demand.

  • Practice questionsWhich statement best describes how a structure's fundamental period affects the seismic base shear computed by the equivalent lateral force procedure?
  • FlashcardsBase shear formula. The total design lateral force V = Cs·W, where Cs is the seismic response coefficient and W is the effective seismic weight of the structure including applicable portions of other loads.
  • Cheat sheetBase shear (ASCE 7 equivalent lateral force): V = Cs·W, where W is the effective seismic weight including dead load plus applicable portions of other loads (e.g., 25% of floor live load in storage areas, partition allowances, snow where specified).
  • Key termsPeak Ground Acceleration (PGA). The largest acceleration the ground experiences during an earthquake, usually expressed as a fraction of gravity.
  • Study planDefine and calculate the fundamental seismic quantities - peak ground acceleration, spectral acceleration, period, and natural frequency - from given site and structure parameters.
  • Common mistakesCandidates carry ASD habits from gravity-design practice into seismic problems, where the base shear and member demands are almost always strength-level, and the exam deliberately offers the service-level result as a distractor.
