Seismic Design: Examples from SEAOC’s Seismic Design Manual based on IBC 2018/ASCE 7-16

The Structural Engineers Association of California (SEAOC) and NCSEA have teamed up to deliver a brand new Web-Based Seminar Series for you on the newly-published Seismic Design Manual. This web-based Seismic Design Seminar will be delivered over six weeks in six 1.5 hour webinars by some of the industry’s best and brightest minds. This Seminar will present on the following topics:

  • Provisions in ASCE 7-16 and 2018 IBC,
  • wood diaphragms,
  • concrete shear walls,
  • diaphragm design,
  • pile foundations and grade beams,
  • steel special moment frames,
  • buckling restrained braced frames,
  • multi-story wood frame structures. 
Each presentation will provide examples of IBC 2018/ASCE 7-16 problems that include a discussion of the provisions in the standard, speaking to big-picture concepts and the nuts, bolts and nails of implementation.

This seminar is critical to practicing structural engineers, trained designers, building department engineers, plan review agencies, professors and students from across the nation as you can all learn from these examples of code-compliant designs engineered to achieve good performance under seismic design.

The registration fee for the Seminar is $495 for members ($800 for nonmembers), which includes all 9 hours of education. Each individual webinar can be purchased separately for $195 for members ($250 for nonmembers). 
  • Purchase all 6 webinars in the Seminar and have access to the recordings for 1 Year.
  • The Seismic Design Manuals (or individual volumes) may also be purchased separately through ICC. 
  • Each seminar purchase is per office location. If your firm is operating remotely, contact NCSEA at on how to accommodate multiple users from the same location.

Please note: These webinars are not included in the NCSEA Webinar Subscription. 

Schedule of Events
Part #1 - Introduction to the Seismic Design Manual, Provisions in ASCE 7-16 and 2018 IBC, and Wood Diaphragms, Presented by Katy Briggs, S.E. and John Lawson, S.E.

This presentation will cover examples from Volume 1 and 2. Volume 1 of the 2018 SSDM focuses on provisions in ASCE 7-16 and the 2018 IBC. This presentation will go through examples in Volume 1 that have been updated as a result of changes from ASCE 7-10 to ASCE 7-16 and from the 2015 IBC to the 2018 IBC. The design example presented from Volume 2 will explore methods to address the high diaphragm shears and the challenges associated with the potentially large deflections. The example will illustrate implementation of the new ASCE 7-16 diaphragm design force provisions as well as a discussion of other new research developments on large diaphragm behavior in these buildings.

Part #2 - Concrete Shear Walls and Diaphragm Design, Presented by Karl Telleen, S.E. and Badri Prasad, S.E. 

This presentation will cover Examples 1 and 7 from Volume 3. Example 1 addresses concrete shear walls, focusing on key concepts including: desired behavior of concrete walls, design for flexure, bar cut-offs and lap splices, design for shear, effect of gravity framing, detailing of wall boundaries, detailing of coupling beams, and wall stiffness. The presentation will draw on observations and lessons learned from past earthquakes, in addition to code requirements and recommendations from research. This presentation will also cover design of diaphragm, chords and collectors using a simplified approach, to comply with the requirements of IBC 2018. Conclusions based on the results are presented at the end of the example. 

Part #3 - Pile Foundations and Grade Beams, Presented by Stephen Harris, S.E. 

The presentation includes a review of Examples 5 and 6 of Volume 3 of the SSDM. Example 5 pertains to the design of a cast-in-place concrete pile foundation. The foundation addressed in the example is a post-tensioned concrete parking garage. However, the pile design methodology is applicable to any building. The presentation includes recommendations for coordination with the geotechnical engineer, determination of the most cost-effective geotechnical pile capacity for the project, determining the number of piles at each location, geotechnical and structural design of the piles to resist vertical and lateral loading, distribution of base shear, review of applicable Code requirements and recommendations for detailing. Example 6 explores three approaches to designing pile foundations that support a moment-resisting frame: stiff grade beam designed for amplified loads; flexible grade beam with ductile detailing; and individual caps resisting moments through pile axial loads.

Part #4 - Steel Special Moment Frames, Presented by Kevin Moore, P.E., S.E., SECB 

Structural steel special moment frames (SMF) are typically comprised of wide flange beams, columns, and beam-column connections. Connections are proportioned and detailed to resist internal forces (flexural, axial and shear) that result from imposed displacement as a result of wind or earthquake ground shaking. The anticipated seismic behavior of the SMF system is long period, high displacement motion, with well distributed inelastic demand shared by all participating beam-column connections. This design example follows the provisions of AISC 358 for the RBS connection type for the steel SMF seismic force resisting system.

Part #5 - Buckling Restrained Braced Frame, Presented by Anindya Dutta, PhD, S.E. and Kenneth Tam, S.E. 

This presentation will address steel seismic design in accordance with the 2018 IBC. Specifically, it will review the Buckling Restrained Braced Frame design example in Volume 4 of the 2018 IBC Structural/Seismic Design Manual. The authors will present the basic code provisions for Buckling Restrained Braces and illustrate through the example how a building can be designed to adhere to those provisions. Specific requirements for conformance demonstration through testing will also be addressed.

Part #6 - Wood Hotel Building (On Foundation), Presented by Doug Thompson, S.E., SECB 

The webinar will be based upon the design example “Four-story Wood Light-frame Structure” in Volume 2 of the SSDM series. This presentation will talk about rigid vs flexible diaphragms and potential problems with torsion in these types of buildings. The presentation will include the design and detailing for a multi-story wood framed shear walls using the continuous tie down system, including boundary element and tension rod design. The presentation will also include how to calculate wood frame shear wall deflections. There will be a brief discussion on the design and detailing of wood framed trusses and the use of collector trusses. The presentation will conclude with a side by side comparison of force-transfer-around-openings (FTAO) using both the Thompson Method and the Diekmann Method.
