**INSTRUCTOR: **

Finley A. Charney, Ph.D., P.E., F.ASCE F.SEI

**Purpose and Background**

This course provides a detailed description of the *ASCE 7-16* procedures for seismic load analysis of buildings and other structures. For buildings, the course begins with a brief history of the development of *ASCE 7* and then presents a sequence of topics that will lead you through the process of determining the seismic hazard, selecting the seismic-force resisting system, evaluating configuration irregularities., and determining the most appropriate method of analysis. Next, requirements for system modeling and structural analysis are presented by example. The last two weeks of the course concentrate on the seismic load analysis of non-building systems and nonstructural components. Significant changes from *ASCE 7-10* to *ASCE 7-16* are highlighted throughout the course.

**Benefits and Learning Outcomes**

Upon completion of this course, you will be able to:

- Discuss the history of the development of the
*ASCE 7*seismic load provisions. - Explain the advantages and disadvantages of different seismic-force resisting systems and select the appropriate system for a structure.
- Identify how to select the appropriate analysis method, and how to model the system for compliance with
*ASCE 7*requirements. - Evaluate the basic procedures for developing seismic loads for nonstructural components and for nonbuilding systems.
- Explain the process of determining the appropriate level of ground motions for use in seismic design and analysis.
- Describe the procedures used for performing Equivalent Lateral Force, Modal Response Spectrum, and Linear Response History Analysis.
- Identify how the presence of configuration irregularities can penalize a design.

**Assessment of Learning Outcomes**

Achievement of the learning outcomes by attendees will be assessed through (3) exams.

**Who Should Attend?**

- Practicing engineers
- Building code officials
- Architects
- Developers

**How to Earn your CEUs/PDHs**

This course is worth 2.4 CEUs/24 PDHs. To receive your certificate of completion, you will need to complete (3) exams and receive a passing score of 70% or higher.

**How do I convert CEUs to PDHs?**

1.0 CEU = 10 PDHs [Example: 0.1 CEU = 1 PDH]
