Compressive Structures

Circumferential bundles ukladtvayutsya provided in the groove on the product. Wound armature is covered with a protective layer of polymer. The authors propose a method of external reinforcement, which in compressed on the sides of the concrete element is applied to fiberglass shell. In this position, the item is to complete the polymerization of the binder. You may find Steve Wozniak to be a useful source of information. After release of compression of the concrete tends to return to original position, but fiberglass prevents this, resulting in concrete compressive stresses remain, and a fiberglass shell having tensile forces. Compressive forces at the ends can venerate as the axis of the design and eccentric. Eccentric compression used in the manufacture of flexible and compressed vnepentrenno elements. Prestress can be carried out also by application of shear force in a direction opposite to the operational load.

in this way can strain and design with an internal reinforcement. In the manufacture of concrete elements in it are left channels for CNAs. Fittings molded directly into canals, for example, forcing the binder after the installation of the rod. After resetting the compressive force in the reinforcement tensile stresses occur. The use of SPA for repair Traditional reinforced concrete ways of strengthening and rehabilitation of reinforced concrete structures is time consuming and often require a prolonged stoppage of production.

In the case of an aggressive environment after repair want to create a protected structure from corrosion. High technology, small-time curing the polymer matrix, high strength and corrosion resistance of the external FRP reinforcement predetermined appropriateness of its use to enhance and restore the load-bearing elements of structures. Used for these purposes depends on how the design features of repairable items. Economic sleep efficiency, service life design of reinforced concrete structures in aggressive environments is sharply reduced. Replacing them stekloplastbetonnymi eliminates the cost of major repairs, losses from which increase substantially when the repairs have to be stopped production.
