Purpose and Background
Prescriptive seismic design of a building is carried out by using judgment-based load reduction R and deflection amplification Cd factors. As a result of these factors, the performance of the building during future earthquakes is not clear either to the engineer or to the owner of the building. In contrast, the performance-based seismic design (PBSD) is carried out by using true strength, deformability and damping of the building to meet specific performance goals of: (1) life safety during rare earthquakes; and (2) business continuity during frequent earthquakes. It is a misconception that the PBSD is more complex than the prescriptive seismic design. Test and analytical knowledge can be used to simplify PBSD. The purpose of this class is to make PBSD accessible to ordinary engineers by demonstrating practical ways of conducting PBSD of buildings.
Real life examples are presented with emphasize on understanding. An intuitive approach is used to describe complex ideas. Questions and discussions are encouraged throughout the class.
Benefits and Learning Outcomes
Upon completion of this course, you will be able to:
- Practice state-of-the-art knowledge in seismic performance

How to Earn your CEUs/PDHs
This course is worth .4 CEU’s /4 PDHs. To receive your certificate of completion, you will need to complete a short on-line post-test and receive a passing score of 70% or higher within 30 days of the course.
How do I convert CEUs to PDHs?
1.0 CEU = 10 PDHs [Example: 0.1 CEU = 1 PDH]
