Seminar Description

The 2021 IBC has already been adopted or is soon to be adopted by major jurisdictions around the country. The 2022 California Building Code, based on the 2021 IBC, is going to be effective on January 1, 2023. Changes in the structural provisions, Chapters 16-23, from the 2018 to the 2021 IBC are discussed and explained in this series of five webinars as follows:

Part 1 - Preliminaries and Chapter 16, Structural Design

The 2018 IBC adopted ASCE 7-16; the 2021 IBC adopts ASCE 7-16 with Supplement No. 1. Thus, the changes in chapter 16 come mainly from Supplement No. 1 and a number of changes to ASCE 7-16 that were not implemented in the 2018 IBC. All significant changes are explained in this first webinar.

Part 2 - Chapters 17, 18, 19, including ACI 318-19 Chapters 1-8

This second webinar explains changes to Chapter 17, Special Inspections and Tests, Chapter 18, Soils and Foundations, and Chapter 19. The reference standard for concrete design and construction has been updated from ACI 318-14 to ACI 318-19 in 2021 IBC Chapter 19, Concrete. This being the most major standard update in the 2021 IBC, changes in ACI 318-19 take up a major portion of these structural seminars. This Part 2 discusses changes in Chapters 1 through 8 of ACI 318-19 (General, Notation and Terminology, Reference Standards, Structural System Requirements, Loads, Structural Analysis, One-Way Slabs, and Two-Way Slabs).

Part 3 - ACI 318-19 Chapter 9 through Section 18.9

This Part 3 discusses changes in ACI 318-19 chapters on Beams, Columns, Walls, Diaphragms, Foundations, Plain Concrete, Beam-Column and Slab-Column Joints, Connections between Members, and Anchoring to Concrete. Additionally discussed are changes in Chapter 18, Earthquake Resistant Structures. The Chapter 18 changes discussed in this part relate to Ordinary, Intermediate, and Special Moment Frames.

Part 4 - ACI 318-19 Section 18.10 through Chapter 22

This webinar discusses the remainder of the changes in Chapter 18 - ones related to Special Shear Walls, Diaphragms, Foundations, and Members Not Designated as Part of the Seismic Force-Resisting System. It also discusses changes in the chapters on Concrete: Design and Durability Requirements; Steel Reinforcement Properties, Durability, and Embedments; Strength Reduction Factors; and Sectional Strength.

Part 5 - ACI 318-19 Chapters 23-27 and Appendix A. 2021 IBC Chapters 22 and 23

This part discusses changes in the remainder of ACI 318-19 Chapter 23 - Strut and Tie Method; 24 -Serviceability, 25 - Reinforcement Details, 26 - Construction Documents and Inspection, 27 - Strength Evaluation of Existing Structures, and Appendix A - Design Verification Using Nonlinear Response History Analysis. Changes in 2021 IBC Chapter 22, Steel and Chapter 23, Wood are also discussed in this part. ANSI/AWC SDPWS – Special Design Provisions for Wind and Seismic was updated from its 2015 to its 2021 edition in the 2021 IBC. Major changes between the two editions are discussed in this webinar.

Speaker Bios

Dr. S. K. Ghosh is known internationally for his work in earthquake engineering. He has influenced seismic design provisions in the United States for many years by serving on or chairing numerous committees and advisory panels. He specializes in the analysis and design, including wind and earthquake resistant design, of reinforced and prestressed concrete structures. Dr. Ghosh is active on many national technical committees and is a fellow of ASCE, SEI, ACI, and PCI. He is a member of ACI Committee 318, Standard Building Code, and the ASCE 7 Standard Committee (Minimum Design Loads for Buildings and Other Structures). He is a former member of the Boards of Direction of the Building Seismic Safety Council (BSSC), the American Concrete Institute (ACI), and the Earthquake Engineering Research Institute (EERI). In addition to authoring many publications in the area of structural design, he has investigated and reported on structural performance in recent earthquakes.

Buddy Showalter, P.E., M.ASCE is a senior staff engineer with the International Code Council's (ICC) product development group. He develops technical resources in support of the structural provisions of the International Building Code and International Residential Code. Showalter reviews publications authored by the Code Council and engineering groups, while also developing publications and technical seminars on the structural provisions of the International Codes for building departments, designers and special inspectors. He is the project lead in the development of Mass Timber Buildings and the IBC and associated education programs, jointly developed by ICC and the American Wood Council (AWC). A graduate of Virginia Tech, Showalter has also been a member of the editorial board for STRUCTURE magazine for more than 15 years. Before joining ICC, Showalter spent 26 years with AWC where he led its technology transfer program with oversight responsibility for publications, website, helpdesk, education and other technical media. He has more than 35 years of experience in the development and support of building codes and standards, publishing more than 60 technical articles for industry-related trade journals.

Kirsten Zeydel, S.E., is the President of ZO Consulting and a Structural Consultant with S.K. Ghosh Associates. She is a licensed Structural Engineer, based in Southern California, with over twenty years of experience in the design of cold-formed steel framing. She has led the structural design of exterior/interior non-load-bearing and load-bearing cold-formed steel framing for buildings across the United States. She has also successfully taken many projects through the rigorous California Office of Statewide Health Planning and Development and the California Division of the State Architect. In practice, Kirsten Zeydel specializes in panelized cold-formed steel construction and the design/coordination of exterior building “skins” in order to ensure they perform as expected during earthquakes and wind events.
