Description

West Virginia State Capitol Building - Structural Repairs to the Inner Dome
This presentation will provide an overview of the investigation, design, and construction of structural repairs to the historic ornamental cast-plaster Inner Dome at the West Virginia State Capitol Building. The Inner Dome was found to be constructed with coffers that were individually cast with gypsum plaster and coconut fiber reinforcement and mounted to a grid using plaster wads reinforced with coconut fiber. WDP performed material testing of the unique plaster components in order to evaluate the behavior of the Inner Dome through 3D finite element analysis. WDP identified deficiencies in the Inner Dome system and designed repairs to stabilize, support, strengthen, and monitor the Inner Dome that were coordinated with the project team to develop a detailed sequencing plan to execute the work.

Presented by: Jodi Knorowski, P.E., and Akshay Beniwal, WDP & Associates

Google Spruce Goose
Arup has transformed the Spruce Goose aircraft hangars built in 1940s and originally used by Howard Hughes into modern office accommodation. The presentation includes the structural design of the overall project and will mainly focus on the retrofit measures taken to bring this 1940s glulam hanger structure to code compliance, including 52 inch long screws, multi-tier buckling resisting braced frames and tie rods to control roof deformations.

Presented by: Patrick Noll, Arup

Course will award 1.5 hours of continuing education for the live session only.
Each series registration is per person.
This will be available as a recording, with no PDH attached.

Thank you to our Sponsor!

Akshay is a Staff Engineer with WDP & Associates Consulting Engineers. He holds a master's degree in structural engineering from the University of California, Irvine. For this project, he conducted the in-house material testing of the coconut reinforced gypsum plaster retrofitted with glass fiber reinforced polymer. He also developed the structural models and finite element analysis of the existing dome structure and the proposed repairs.
Patrick Noll

Patrick Noll is an Associate with Arup in Los Angeles. After a three-year apprenticeship to become a professional carpenter, he received his diploma in structural engineering from University of Applied Science in Muenster, Germany and his Master of Science in Timber Engineering from Napier University in Edinburgh, United Kingdom. Prior to joining the Arup office in Los Angeles in 2010, he worked for Arup in Germany.Patrick had always a major interest in timber construction, and it was a perfect fit to work on the Google Spruce Project and the retrofit of this historic 1940s glulam aircraft hangar. He is currently leading the structural engineering efforts for the Modernization project of Terminal 2 and 3 at Los Angeles World Airports for Delta Airlines. Other projects include the Samsung Headquarters in San Jose, CA, and the Allegiant Stadium in Las Vegas, NV.
