Navigating the Uncertainty: Exploring Seismic Certification of Nonstructural Components
Seismic certification of nonstructural components remains an imprecise practice, presenting challenges for those responsible for ensuring the safety, operation, and resilience of facilities and systems following a large earthquake event. These components vary in size and complexity, from electronics cabinets and switchgear to air-handlers and chillers, making a standardized certification process virtually impossible. Many manufacturers, vendors, and engineers offer seismically certified equipment, but project teams often have questions: What is actually being certified? What does it mean to be certified? Is there a defined performance standard?
In this webinar, we will delve into the complexities surrounding the seismic performance and certification of nonstructural components within the framework of building codes and design standards. We will explore how building codes address seismic resilience and the diverse methodologies that project teams can use to demonstrate seismic adequacy. Through a series of insights and examples to illustrate the nuances of the certification process, we will share lessons learned on how to adequately specify the appropriate seismic performance level needed for all nonstructural components.

About the Speaker
William (Bill) Bruin has extensive experience in risk consulting, structural engineering, and project management applied over a variety of industrial, offshore, and marine projects, primarily in the oil and gas industry. His career has focused on condition assessment, response evaluation, risk identification, hazard mitigation, due-diligence assessment, and design for a wide variety of onshore, near-shore, and offshore structures and facilities. Bill is committed to advancing and giving back to the profession. He is active with several American Society of Civil Engineers (ASCE) committees, including the standards committee for ASCE-61 Seismic Design of Piers and Wharves, and has traveled to disaster locations for earthquake and tsunami reconnaissance.
Derrick Watkins has specialized experience designing, analyzing, constructing, and repairing structures. His subject matter expertise includes complex finite element analysis, seismic design for extreme earthquake events, design of rotating and vibrating equipment supports and foundations, pressure vessels and liquid storage tanks, vibration mitigation, impact and blast considerations, aircraft impact assessment, anchorage to concrete, and equipment seismic testing and certification. He has helped to pioneer and standardize procedures and reporting for seismic certification of nonstructural components. He is an active member of several code committees, including the ASCE Committee 4 on Seismic Analysis of Safety-Related Nuclear Structures and Committee 43 on Seismic Design Criteria for Structures, Systems, and Components in Nuclear Facilities.
