Abstract: A connector for joining concrete structures such as double tee beams to one another. The connector includes a curved bolt that is formed with a shape memory alloy. Through utilization of the bolt, a joint can be post-tensioned following assembly through application of heat to the joint. Post-tensioning can be reapplied following loosening of the joint through application of heat. When considering a super elastic shape memory alloy, the bolt can be a smart bolt that can self-correct following deformation due to excessive load.
