Abstract: A method of making a fiber reinforced hoop includes forming two plates having a face opposing one another and defining an outer periphery with a recessed groove to define a channel between the two plates. Fibrous strands coated with an adhesive are wrapped around the two plates within the channel a plurality of times. The adhesive is allowed to cure so that the fibrous strands form a rigid hoop. In a particular embodiment, the two plates are connected to a rotary spindle to rotate the two plates a plurality of times as the fibrous strands are fed into the channel. In a still further embodiment, multiple plate sets can be mounted to rotate with the spindle and fibrous strands can be wound into the channels in each of the plate sets so that multiple hoops can be formed and cured simultaneously.

Abstract: A connecting system for connecting concrete beams of a parking structure including a pair of concrete beams and a plurality of spring-like connectors connected between the pair of concrete beams. The concrete beams are each provided with an aperture and the spring-like connector is in a form of a pre-formed carbon fiber bundle or metal and has opposite ends that are secured in the apertures in the concrete beams by an adhesive.

Abstract: A method of repairing concrete having a crack, including cutting an elongated slot across the crack. Inserting an elongated rigid grid into the slot to extend across the crack, the rigid grid having a length dimension greater than a width dimension which is greater than a thickness dimension, the rigid grid defining a plurality of openings there through that extend toward opposites sides of the slot; and adhering the elongated rigid grid in the slot with an adhesive that flows into at least some of the plurality of openings. The rigid grid can be formed from a rigidified fabric grid, a wire mesh, or metal.

Abstract: A reinforcement system includes a structural member such as a concrete wall including a pair of holes formed therein. A fiber reinforcement strip is adhered to the structural member between the pair of holes. A U-shaped bracket includes a pair of legs being secured in the pair of holes and a bridge portion that overlaps an the fiber reinforcement strip, a secondary reinforcement strip can be used to distribute forces from the bridge portion of the bracket along a length of the fiber reinforcement strip.

Abstract: A method of straightening a block wall having an inwardly bowed shape in a central region between an upper end and a lower end includes mounting a tensile member between the upper end and the lower end of the block wall. A tension force is applied on the tensile member to apply a compression force on the bowed block wall for a period of time until the bow in the block wall is straightened to a desired amount. Once the bowed block wall is straightened by a desired amount, a reinforcement member is applied to the straightened block wall.
