Part 1: ASCE 7-22’s Effect on Non-Structural Component Seismic Loads

ASCE 7-22 introduces substantial modifications to the way seismic forces on non-structural elements are determined. Are the calculations more difficult? Are the loads higher? What information is needed to determine the loads? How will these modifications affect non-load-bearing CFS interior and exterior framing, along with their connections? This presentation will address these questions and provide advice on what we should tell our contractor clients to anticipate regarding these code changes.

Part 2: Seismic Drift Accommodation of Interior Partitions - Fragility Based Comparison w/ FEMA P-58

Expected performance of interior partitions after a seismic drift event is often not well understood. In some cases, projects will require systems that add construction cost and may not actually offer performance benefit. FEMA P-58 background documents provide useful data that can be used to compare the expected fragility of different drift systems. This presentation will provide an overview of the FEMA P-58 background documentation which can help inform interior partition drift accommodation decisions on projects.

Karl L. Schroeder, P.E.
Devco Engineering, Inc

Karl Schroeder is a Senior Project Engineer with Devco Engineering, Inc and has been with the company since 2006. He has designed the cold-formed steel scope on a wide variety of projects including colleges/universities, military and government facilities, hospitals, schools, airports, museums, stadiums, and various other commercial buildings. Some of his specialized experience includes blast design, Risk Category V seismic design, California HCAI and DSA projects, Alaskan arctic facilities, and sound isolation design. He typically works directly with the contractor, which requires extra attention to constructability and economic solutions for the framing systems.

Soon after graduating from Oregon State University with a Bachelor of Science degree in Civil Engineering, Karl was given an opportunity with Devco Engineering to specialize in cold-formed steel framing. Karl earned his California PE licensure in 2009 with various other states following. From 2009-2016, Karl represented Devco Engineering as a member of the American Iron and Steel Institute (AISI) Committee on Specifications. In 2015, Karl opened a branch office of Devco Engineering in Bozeman, Montana where they continue to serve cold-formed steel focused projects. He is a member of the CFSEI Executive Committee.

Kirsten Zeydel, S.E.
Nevell Group, Inc.

Kirsten Zeydel, S.E. is the director of design at Novell Group Inc. She is a registered structural engineer in California with over 22 years of structural engineering design and management experience. She specializes in cold-formed steel (CFS) design, detailing, and panelization. Kirsten led the structural engineering group at a startup company where she developed a QA/QC process acceptable to OSHPD, and obtained IAPMO product certification for the framing members, sheathed panels, and pre-finished exterior panels. Her extensive experience in CFS design includes a dorm project with nine multi-story CFS load bearing buildings totaling 800,000-sq-ft, and the CFS non-load bearing interior and exterior framing for a 550,000-sq-ft hospital in California. In addition to the engineering side of CFS design, Kirsten has experience with quality programs, product certification, welding procedures, architectural building code requirements and prefinished exterior panels. Kirsten is a former member of the CFSEI Executive Committee. She is also a proud wife and mother of two children who firmly believes that being a mom has made her a better engineer.
