Proposed Design of a CFRP Flange-to-Flange Connection for Precast Prestressed Double Tee Systems
Publication: Journal of Composites for Construction
Volume 11, Issue 1
Abstract
The current methods of connecting the flanges of precast double tee members, and their respective short comings in specific situations, are described. A new carbon fiber-reinforced polymer (CFRP) flange-to-flange connection is proposed to eliminate the problems associated with repair requirements for the current connections. Design expressions for the currently used mechanical anchorage and the proposed CFRP connection are presented. A comparative calculation for the two systems is given.
