Wednesday: March 11th & 18th 5:00 PM - 8:00 PM

Come learn about updates to the recently adopted 2019 California Building Code and stay current with your building code knowledge. The seminar will cover a broad variety of updates from loading to material specific provisions.


Night 1, March 11th:

Seismic Related Updates to ASCE 7-16: Rafael Sabelli, SE – Walter P Moore

  • The 2016 edition of ASCE 7 as now the standard used in the California Building Code, replacing the 2010 edition. The latest edition includes numerous changes related to seismic design, including changes to the seismic spectrum, diaphragm-design methods, and nonlinear response-history analysis. The presentation highlights the new material and changes in the standard.

Changes to AISC 341 Seismic Provisions for Structural Steel Buildings: Jim Malley, SE - Degenkolb

  • This presentation will discuss the major new features of the 2016 AISC Seismic Provisions (AISC 314-16), which is included by reference in ASCE 7-16 and therefore the 2018 IBC structural provisions, hopefully assisting in making the transition to this new standard. The latest edition of AISC 341, dated 2016, has been available since 2017. The document has significant technical modifications including new material specifications, use of steel braced diaphragms, new column splice details, requirements for SCBF gusset plate welds, and application of demands on columns that participate in intersecting frames. In addition, discussion of significant new provisions related to the seismic design of multi-tier braced frames will be provided. A new composite shear wall system has also been developed. Some high-level discussion of changes to AISC 360 “Specification for Structural Steel Buildings” will also be presented, as will any California specific changes that are included in the 2020 California Building Code.

2019 CBC Changes to Cold Formed Steel Design: Jeff Ellis, SE – Simpson StrongTie

  • Changes to the 2019 CBC for cold-formed steel design include a reorganization of the AISI specification and consolidation of most of the AISI framing standards into two standards. These changes are to improve understanding, use, and development as well as for better harmony between the AISI and AISC provisions. Additionally, there are some significant technical changes for the design of cold-formed steel. This presentation will discuss the reorganization and technical changes so the attendee’s may update their CFS design and detailing practices accordingly.    

Night 2: March 18th:

Geotechnical Updates relating to Structures in ASCE 7-16: Debra Murphy, PE & Darcie Maffioli, PE/GE – Slate Geotechnical

  • Each new code cycle introduces updated approaches to performing geotechnical and ground motion analysis.  The recent adoption of the 2019 CBC comes with notable changes in the assessment of foundations particularly for sites subject to liquefaction and the derivation of code derived and site-specific response spectra.  We will present to you an overview of these changes and a synopsis of what to expect from CBC 2019 compliant geotechnical recommendations.  

2019 CBC DSA Amendments – Structural Safety: Bryan Frank, SE - DSA

  • The Division of the State Architect (DSA) is the jurisdictional authority in the state of California for the approval of plans and supervision of construction at public K-12 schools, community colleges, and state-owned essential service facilities.  Consistent with this authority, each version of the California Building Code (CBC) includes amendments authored by DSA specific to these categories of buildings and/or structures.  This talk will provide a basic overview of the organization of DSA amendments within the CBC, highlight various amendments of interest, and focus on changes in the 2019 CBC amendments relative to those in the previous version of the CBC (2016).  Content will be limited to DSA amendments relevant to Structural Safety provisions, as amendments specific to Accessibility and Fire/Life Safety provisions are outside the scope of this talk.

  2019 CBC Updates to Wood Framed Construction: Kelly Cobeen, SE - Wiss, Janney, Elstner Associates

  • The wood design provisions of the 2019 California Building Code (CBC) incorporate the new 2018 edition of the National Design Specification for Wood Construction (NDS), while retaining the 2015 edition of the Special Design Provisions for Wind and Seismic (SDPWS). This presentation will provide an overview of significant changes in the 2019 CBC and 2018 NDS that are of interest to designers of wood-frame structures. The presentation will conclude with a brief overview of future directions for wind and seismic design based on the nearly complete 2021 Edition of the SDPWS.

He is active in the development of seismic design standards for steel systems and is vice-chair of the AISC Seismic Provisions Committee. He is a member of the ASCE 7 Seismic Task Committee and the NIST Building Seismic Safety Council’s Provisions Update Committee. Rafael is the chair of the AISC Structural/Seismic Design Manual committee and was the Project manager for the SEAOC Seismic Design Manual.  Rafael is co-author of Ductile Design of Steel Structures and has written extensively on the design and behavior of steel seismic systems. His paper on efficient design for stability, “The Indirect Analysis Method,” is coming out in the next (2020 Q2) issue of the AISC Engineering Journal.He is currently President of the Structural Engineers Association of California and would be speaking about steel if it were not for Jim Malley. Oh, well.
