Ohio State University - Interdisciplinary Research Facility
The 5-story cast in place concrete frame constructed by Lithko Contracting relied on CobiaxUSA 17” SL voided flat plate slabs to address the rigorous vibration requirements of 2,000 mips (micro-inches per second) while allowing spans in the 30 ft range.
PROJECT VOIDED SLAB ACHIEVEMENTS:
Voided slabs calm vibration issues.
Voided Flat Plate provides beam free frame with more available clear space resulting in 30’x30’ bays.
A 17” slab flat plate voided slab was selected with a lower weight of about 30%.
Inherent fireproofing with concrete structure.
Vibration considerations required the slab to tolerate a vibrational velocity of, 2000 MIPS (micro-inches-per-second).
The Interdisciplinary Research Facility designed by Architects Moody Nolan, Inc. / Pelli Clarke Pelli envisions an innovative and modern environment to serve multiple disciplines. The project will house approximately 305,000 new square feet and will support the university’s advances in multiple research disciplines, including biomedical, life sciences, engineering, and environmental sciences, among others. In addition, two floors will be dedicated to The Ohio State University Comprehensive Cancer Center including its new Pelotonia Institute for Immuno-Oncology.
The use of voided slabs provide a balance between stiffness while reducing the floor mass by as much as 35%.
