WEBINAR ON NOVEL COMPOSITE STEEL FLOOR SYSTEM - FASTFLOOR R
August 28, 2025 | 3:00 p.m. Eastern
Presenter: Benjamin W. Schafer, Ph.D., P.E. Johns Hopkins University
This webinar investigates the structural performance of a novel, nonproprietary composite steel floor system designed for rapid assembly in residential and similar applications.
The primary version of the system comprises two opposing 3-inch-deep, 18-gauge steel decks forming a closed cell, topped with a cementitious panel and optional non-structural finishes. A series of full-scale tests were conducted—spanning bare to fully finished assemblies—under both vibration and four-point bending to evaluate dynamic and flexural behavior. Floor vibration testing was performed at each construction stage using multiple accelerometers, and preliminary results indicate clear pathways to achieving successful vibration performance. Results show that the cementitious panel significantly enhances stiffness and strength of the assembly. Observed local buckling in the steel deck prior to failure highlights the importance of composite action, and ongoing efforts aim to refine end details and explore alternative configurations for broader application.
This webinar will discuss these findings and initial design ideas for the development of this new floor system.
