Building Seismic Safety Council Webinars

BSSC Webinar Series

The National Institute of Building Sciences Building Seismic Safety Council (BSSC) will host, under the sponsorship of the Federal Emergency Management Agency (FEMA), a new 2017 webinar series focused on construction materials addressed in the National Earthquake Hazards Reduction Program (NEHRP) publications.

All of the webinars are free and open to the broad disaster community and the public. Topics and presenters are listed below. Additional dates, times and information on how to access to the webinar site will be broadcast in future announcements.

NOTE: The opinions expressed in the webinar presentations are those of the authors, and do not necessarily reflect the views or policies of the BSSC, FEMA or USGS.

2016 BSSC Webinars


September 28, 2016
Response Spectrum Analysis Method and Linear Response History Analysis Method
The Response Spectrum Analysis (RSA) method has been widely used for the dynamic analysis of structures since the 1950’s. This webinar focused on updated requirements to both the RSA method and Linear Response History (LRH) analysis method in the National Earthquake Hazards Reduction Program’s (NEHRP) 2015 NEHRP Recommended Seismic Provisions and ASCE/SEI 7-16, Minimum Design Loads for Buildings and Other Structures. James O. Malley, SE, senior principal with Degenkolb Engineers, addressed RSA procedures in ASCE 7, and Finley Charney, PhD, PE, professor of structural engineering at Virginia Tech and president of Advanced Structural Concepts, Inc., talked about the revision of Chapter 16 of ASCE 7-16 and moving LRH to Chapter 12. Download Malley’s presentation. Download Charney’s presentation.

Seismic Isolation Design with the 2015 NEHRP Recommended Provisions
Seismic isolation is perhaps the most effective method available for protecting structures from earthquake damage. The National Earthquake Hazards Reduction Program (NEHRP) 2015 NEHRP Recommended Seismic Provisions for Buildings and Other Structures contain updated requirements for the design and testing of seismic isolation systems and the design of isolated superstructures. Presenter Andrew W. Taylor, PhD, SE, FACI, began with an introduction to seismic isolation theory and systems, followed by a review of the seismic isolation design process, with emphasis on the revised requirements in the 2015 Provisions. He presented a design example, and closed the webinar with a discussion of the properties of seismic isolation systems, including the variability of properties and seismic isolation testing requirements.

2015 NEHRP Design Examples

Presented by Robert G. Pekelnicky, PE, a principal of Degenkolb Engineers in San Francisco, member of the BSSC Provisions Update Committee and chair of Project 17’s Acceptable Risk Work Group, this webinar provided an overview of the National Earthquake Hazards Reduction Program’s (NEHRP) NEHRP Recommended Provisions: Design Examples, which are written to illustrate and explain the applications of the 2015 NEHRP Recommended Seismic Provisions for Buildings and Other Structures, ASCE 7-16 Minimum Design Loads for Buildings and Other Structures and the material design standards referenced in both documents. Download Pekelnicky's presentation (PDF).

April 28, 2016
Nonlinear Response-History Analysis
, presented by Curt B. Haselton, PhD, PE, professor of civil engineering at the California State University, Chico, highlights content in the National Earthquake Hazards Reduction Program’s (NEHRP) 2015 NEHRP Recommended Seismic Provisions and ASCE/SEI 7-16, Minimum Design Loads for Buildings and Other Structures. Professor Haselton presents his research on Chapter 16: Nonlinear Response-History Analysis for the Design of New Buildings, which focuses on issues of ground motion selection and scaling, nonlinear structural modeling and collapse simulation, as well as the treatment of uncertainties (in both the ground motion and the structural modeling).
