CONFINEMENT REINFORCEMENT FOR MASONRY AND CONCRETE STRUCTURES

摘要

The present invention provides confinement methods for masonry and concrete structures for both new or existing structures. In addition to strength enhancement, the main benefit is found from confinement that changes the fundamentally brittle behavior to a very ductile behavior capable of dissipating energy and surviving the effects of dynamic loading. The confining reinforcement serves as temperature and shrinkage reinforcement as well as shear and flexural reinforcement. When used in conjunction with surface wrap, the current invention enhances the benefit of surface wrap and enable the use of the wrapping technique on noncircular cross sections in order to increase the strength, ductility and energy dissipation of concrete and masonry construction.
