Overview
The FEMA guidelines presented in this course provide a basic framework for the earthquake design and evaluation of dams. The general philosophy and principles for each part of the framework are described in sufficient detail to achieve a reasonable degree of uniformity in application among the Federal agencies involved in the planning, design, construction, operation, maintenance, and regulation of dams. The guidelines deal only with the general concepts and leave the decisions on specific criteria and procedures for accomplishing this work up to each agency. Because these guidelines generally reflect current practices, it will be necessary to make periodic revisions, additions, and deletions to incorporate state-of-the- practice earthquake engineering.
The student must take a multiple-choice quiz consisting of twenty-five (25) questions at the end of this course to earn PDH credits.
Specific Knowledge or Skill Obtained
This course teaches the following specific knowledge and skills:
- The document contains general guidelines for specifying design
earthquake loadings (for design or safety evaluation) and performing
seismic analyses for the design of new dams (for evaluating the safety
of existing dams or modifying existing dams). The guidelines are
presented in four parts:
- Selection of design or safety evaluation earthquakes
- Characterization of ground motions
- Seismic analyses of the dams and foundations
- Evaluation of structural adequacy for earthquake loading
- Review of design earthquake and design procedures
- Operating Basis Earthquake (OBE)
- Maximum Design Earthquake (MDE)
- Maximum Credible Earthquake (MCE)
- Deterministic Seismic Hazard Analysis (DSHA)
- Probabilistic Seismic Hazard Analysis (PSHA)
- Review of various Dynamic Procedures
- Linear-elastic modal superposition analysis method
- Linear-elastic response spectrum methods
- Non-linear time-history methods
- Linear-elastic time-history methods
