摘要： The present disclosure discloses a Fiber Reinforced Polymer/Plastic (FRP) composite spiral stirrup confined concrete column and a compression design method. The FRP composite spiral stirrup includes an internal FRP spiral stirrup and an external FRP square stirrup. In the form of the FRP composite spiral stirrup, effective transverse stress transfer is established by effectively binding stirrups, which can give full play to the mechanical properties of the FRP bars, provide “dual confinement” for core concrete, and greatly improve the peak stress of the core concrete. Confining mechanisms of the FRP composite spiral stirrup to the concrete in different areas are analyzed, a confinement model and a bearing capacity calculation method for the FRP composite spiral stirrup confined concrete column are proposed, and a design method for the FRP composite spiral stirrup confined concrete column is proposed after an accurate calculation method for the bearing capacity is obtained.

摘要： A structural assembly utilizing a reinforced concrete support element with a flexibly-braided reinforcement sleeve and a cable system for building structures. The reinforced concrete BMASS element has an approximately cylindrical shape and includes a substantially solid concrete core. An outer reinforcement sleeve with a flexible multi-axially braided configuration is embedded on the perimeter, and an inner reinforcement sleeve is embedded within the outer sleeve. A cable tension system connected between the ends of the BMASS element transmits tensile force from the cable to the BMASS element. The structural assembly can be configured as a beam or a column. In a beam configuration, the tensioned cable can also provide beam curvature and greater strength. A multi-cable embodiment includes a second cable, providing additional strength and greater ability to control curvature. One or more of the braces may include an adjustable arm. The tension may be adjusted manually, or remotely.

摘要： Provided are a method of manufacturing a three-dimensional textile reinforcement material and a method of constructing a textile reinforced concrete structure using a three-dimensional textile reinforcement material. A two-dimensional grid is bent into a three-dimensional shape using a two-dimensionally woven or knitted textile grid, and the bent grid is coupled with at least one two-dimensional grid, and thus the three-dimensional textile reinforcement material can be simply and easily formed. The three-dimensional textile reinforcement material can be formed by coating the coupled two-dimensional grid and a three-dimensional grid with a thermosetting resin and curing the coupled grids to support a concrete pouring pressure. The three-dimensional textile reinforcement material is formed in a truss material, and the three-dimensional textile reinforcement material with high bending strength can be manufactured, thus a concrete pouring pressure can be supported when a textile reinforced concrete structure is constructed using the three-dimensional textile reinforcement material.

摘要： The present disclosure provides a concrete structure strengthened using a grid reinforcement material and non-shrink grout and a method of strengthening the same in which, when strengthening a concrete structure such as a concrete slab or a concrete wall body that is damaged or deteriorated, a grid reinforcement material is mounted on one side of the concrete structure, a formwork is formed on an outer side of the grid reinforcement material to have a required gap, and then the gap is filled with non-shrink grout so that the non-shrink grout is cured therein to strengthen the old concrete structure, thereby being able to automatically fill and repair cracks formed in the concrete structure just by injecting the non-shrink grout without separately performing crack repair on the old concrete structure. Also, the grid reinforcement material may be easily fixed or mounted using a grid fixing device and may be easily applied to strengthening of a concrete structure having a curved surface as well as a concrete structure having a flat surface such as a concrete slab or a concrete wall body. In addition, reinforcing bars may be additionally arranged in a gap between a surface of the concrete structure and the grid reinforcement material so that the grid reinforcement material increases a cover thickness, and thus the concrete structure is remarkably strengthened.

The void former unit comprises a first void former element comprising a first surface and a first opening in the first surface and a second void former element comprising a second surface and a second opening in the second surface, wherein the first void former element and the second void former element detachably connect to form a passage between the first opening and the second opening, and a void space between the first surface and the second surface surrounding the passage. Multiple void former units can detachably connect to form a void former system comprising a single continuous void space. While exemplified by use in concrete elements, other uses of the void former unit and void former system are envisaged.
