Roles and Responsibilities for Success in Cold Formed Steel Framing
For a project to be successful, it takes more than good number crunching by an engineer. The engineer is only one part of a much larger team working together to design and construct the project. Sometimes, the lines of responsibility can be unclear, leading to delays, arguments and stress. Who is responsible for what? How is the burden of responsibility determined in cold-formed steel (CFS) design and construction practice? This seminar will introduce and share recent updates to the AISI Code of Standard Practice (COSP), discuss the contents of the COSP as it applies to a typical CFS project, and answer participant questions by way of an expert in both CFS design and CFS project management.

An Overview of Changes in the 2021 IBC
The 2021 IBC was published in October 2020. The 2022 California Building Code, based on the 2021 IBC, went into effect in California on January 1, 2023. This presentation provides an overview of the structural changes from the 2018 to the 2021 IBC. ASCE 7-16 remains the reference standard for design loads; however, Supplement No. 1 to ASCE 7-16 is adopted. This supplement is explained at the seminar. Some ASCE 7-16 changes not adopted by the 2018 IBC are now adopted by the 2021 IBC. The design load combinations are no longer in the IBC, except for the alternative basic ASD load combinations. For everything else, a reference is made to ASCE 7-16. Significant changes in Chapter 17, Special Inspections and Tests, and Chapter 18, Soils and Foundations, are discussed. The reference standard for concrete design and construction is updated to ACI 318-19. The very significant and substantive changes in this standard are outlined. In view of the importance of these changes, a significant portion of this seminar is devoted to these changes.

An Overview of Changes in the ASCE 7-22 - Dr. SK Ghosh, PE, SE
ASCE 7-22 was published in the summer of 2022. It will be adopted by the 2024 IBC. The 2025 California Building Code, based on the 2024 IBC, will go into effect in California in January 2026. Thus, ASCE 7-22 will not be required to be used in design in most of the country for the next two to three years. However, the changes from ASCE 7-16 to ASCE 7-22 are so numerous and so substantive that learning about them needs to start now. The chapter on rain loads is the only chapter that has escaped any change. There are huge changes in snow load, ice load, and tsunami load provisions. Fortunately, those are of little or no interest in Arizona. There is a whole new chapter (32) on tornado loads. Risk Category III or IV structures located in the tornado-prone region shown in a figure are required to be designed and constructed to resist the greater of the tornado loads determined in accordance with Chapter 32 or the wind loads determined in accordance with Chapters 26 through 31. Fortunately, again, Arizona is outside of the tornado prone region. Attention in this seminar will be focused on changes in Chapters 11-23 on earthquake loads and Chapters 26-31 on wind loads. The changes in these chapters are many and many of the seismic changes mark significant departures from past practice. All the significant changes will be discussed. Also discussed will be ASCE 7-22 load combinations and importance factors, which are quite different because of changes in the loads chapters.
UC Berkeley New BioSciences Hub
The building formerly known as the Berkeley Art Museum (BAM), designed by Mario Ciampi and opened in 1971, is an architecturally significant Brutalist reinforced concrete building listed on the National Register of Historic Places and designated as a Historic Landmark by the City of Berkeley.
As a successful adaptive reuse, the transformation of this landmark museum building into biosciences incubator and research labs is desirable from both a historical and sustainability perspective. The challenges of the project include incorporating an effective seismic retrofit into a very complicated non-orthogonal three-dimensional space, preserving the historic exposed concrete structure as much as possible, replacement of almost all M/E/P and Fire Safety systems, roofing and skylights, and upgrades to accessibility.
ASCE 41 Standard Nonlinear Dynamic Procedure was used for the seismic evaluation of the existing structure and the retrofit design including the effects of the deep foundations utilizing the Performance-Based Design approach.

CLT Shear Wall and Diaphragm Design
The use of cross-laminated timber (CLT) as a gravity load bearing floor and roof assembly has seen incredible growth in the U.S. over the past decade. However, its use as part of a wind or seismic force-resisting system – either as a shear wall or diaphragm – has only recently been codified. Until recently, this has resulted in designing CLT lateral force-resisting systems through alternate means. This presentation will introduce the new provisions for CLT shear wall and diaphragm design contained in the American Wood Council’s 2021 Special Design Provisions for Wind & Seismic (SDPWS). Items covered will include the detailing and design requirements for the newly recognized CLT shear walls and diaphragms found in the 2021 SDPWS and the range of seismic design parameters (i.e., “R” values) found for CLT shear walls in the American Society of Civil Engineers’ recently published Minimum Design Loads and Associated Criteria for Buildings and Other Structures (ASCE 7-22).

FRP Collector Strengthening in a California Hospital
Seton Medical Center was built in 1965 for the Daughters of Charity to support an underserved community a few miles south of San Francisco in northern San Mateo County. The hospital remains dedicated to serving this community today but had fallen behind in meeting the California state-mandated seismic life safety performance requirements. A seismic evaluation from 2015 identified various seismic deficiencies that included non-ductile concrete columns, and inadequate collectors. But after a few years of financial setbacks and a change in ownership the facility still had not started in on the necessary seismic corrections, and was running short on time.
In the spring of 2020, with the facility under new ownership, the project began again under a tight deadline. The design team identified re-designing the collectors with externally bonded fiber-reinforced polymer (FRP) as a way to reduce construction schedule and risk. Although FRP had been used in this application before, it had not been officially adopted into the California Building Code, nor had it been used on an acute care hospital building in California. With the help of Simpson Strong-Tie, scaled testing was completed to determine project specific design and detailing of the FRP collectors. After a rigorous review with the California Department of Health Care Access (HCAI, formerly OSHPD) the FRP collector design was approved. Simpson Strong-Tie continued to provide support for the project through construction. The switch to FRP proved its value with the flexibility of the material to work around existing conditions, and by keeping construction to the top side of the floor and out of congested ceiling spaces.
