Speaker: Jay Thomas - Vice President for Structural Preservation Systems, Inc.
Bio: Jay Thomas is Vice President for Structural Preservation Systems, Inc.; the largest dedicated concrete repair contractor in the United States and a recognized industry leader. Jay has 22 years of construction experience in commercial and industrial facilities on rehabilitation and maintenance projects involving structural repair, strengthening and protection of concrete and steel.
He has written a number of articles and papers on strengthening techniques and composite strengthening for concrete structures, has been involved in over 400 composite strengthening projects, and has also presented the subject at major industry events, engineering organization seminars, and trade show seminars such as the World of Concrete. Jay is a graduate engineer from the University of Pennsylvania. Professional Memberships include: ACI 440 (FRP), ACI 546 (REPAIR), ACI 437 (STRENGTH EVALUATION OF EXISTING BLDGS.), and International Concrete Repair Institute (ICRI). He was the 2000 recipient of the ACI Construction Practice Award “for co-authored papers, ‘Strengthening Concrete Structures: Parts I and II,’ March and April 1998, Concrete International, which summarize the materials and methods now available for the repair and strengthening of concrete elements in our existing infrastructure.”
Topic: Although the analysis and upgrade of concrete structures is somewhat of a “scientific art” that has been practiced for many years it has evolved into a complex science that requires a blend of engineering, material science and construction perspectives. Strengthening projects may utilize traditional materials such as conventional cement-based and steel materials as well as advanced composite materials (FRP’s) that are commonly used for aerospace applications. The techniques used to design and install these materials for upgrade applications are not common to the engineering and general construction industry which can make strengthening projects even more challenging and complex than new construction.
There are many factors that create the need for strengthening. They include construction and design errors, increase in live load, new code requirements, low concrete strength, voids created during concrete placement, new penetrations and prevention of progressive collapse from blast loads.
This presentation will describe the design strategies, different techniques, materials and design concepts used for upgrading concrete structures. The use of each technique will be illustrated through actual case studies.
