A construction process for enhancing or repairing a concrete floor structure that includes a carbon fiber grid as a reinforcement component is disclosed. The process includes forming a trench at a top surface of the concrete floor structure, and placing a reinforcement material in the formed trench. Then, a concrete bonding agent is applied into the trench. Then, the trench is filled with concrete. As a result, the concrete floor structure is enhanced or repaired to have at least one additional reinforcement component other than the carbon fiber grid.

An improved composite material used to connect, strengthen and/or repair concrete. The improved composite material includes a first fiber system including at least one fiber layer. Each fiber layer includes a plurality of fibers. The binding material can be used to optionally secure together the plurality of fibers. The improved composite material is positioned and secured in a slot cut in a concrete structure. The top edge of the improved composite material includes a recess portion.

A strut may be interposed between a first floor plate and a second floor plate of a multi-story building, wherein the first floor plate is disposed overtop of the second floor plate. The strut includes a first post section and a second post section. The first post section includes a first portion that is coaxial with, annular to and slidably disposed within a second portion of the second post section. A damping actuator is interposed between the first post section and the second post section, and is arranged to dynamically control a position of the first post section in relation to the second post section. The strut also includes an accelerometer. A controller is in communication with the accelerometer and the damping actuator, and controls the damping actuator to control the position of the first post section in relation to the second post section.

An automatic tensioning system for strengthening a beam, a slab and a column by a pre-stressed FRP plate comprises a tensioning end anchor (1), a fixed end anchor (10), and a tensioning bracket (3) connected to the tensioning end anchor (1). A centre-hole jack (16) is provided in the middle of the tensioning bracket (3), a threaded rod (8) passes through the tensioning bracket (3) and is then connected to the centre-hole jack (16), and an upper toothed nut (13) and a lower toothed nut (19) respectively driven by a driving mechanism are provided on two sides of the tensioning bracket (3) on the threaded rod (8). A binary clip-type fixture (4) is further comprised, an upper surface thereof is provided with a cylinder (6), and a sleeve (7) nested outside the cylinder (6) is connected to the threaded rod (8).

A building structure having at least one storey including at least one column; at least one brace attached at one end to one side of at least one of the columns and at a second end to a fixed foundation surface; the brace attached to the at least one column at an incline; the at least one brace having a first portion and a second portion; wherein the at least one brace has a first in-use configuration in which the first portion is freely moveable with respect to the second portion such that a gap is formed in the brace preventing the transmission of force axially along the brace by preventing tensional forces from travelling axially along the brace, and a second in-use configuration in which the gap is closed by the first portion and the second portion being in contact to permit the transmission of forces axially along the brace; and wherein the second in-use configuration allows compressive forces to be transmitted along the brace such that the brace is activated when sufficient deformation occurs in the column in a direction that compresses the brace; and further comprising at least one damper functionally connected to one or both of the first and second portions and configured to provide damping as the at least one brace moves from the first in-use configuration to the second in-use configuration.

The sub-floor brace for abating squeaking floors is a structural element that is configured for use with a supported flooring. The sub-floor brace for abating squeaking floors supports the supported flooring from the ceiling side of the supported flooring. The sub-floor brace for abating squeaking floors supplements the load carrying capacity of the joists that are supporting the supported flooring by creating a load path from the supported flooring to a supporting flooring located in an inferior location to the supported flooring. The supplemental load paths created by the sub-floor brace for abating squeaking floors reduce the squeaking noise commonly associated with aging floors. The sub-floor brace for abating squeaking floors is a telescopic structure that comprises a first support, a second support, and a fastener. The fastener attaches the first support to the second support.
