Retrofitting of Buildings and Structures<\/h1>\n

Externally bonded steel plates, steel or reinforced concrete jackets, and external pre-stressing were the traditional techniques used to strengthen or retrofit existing concrete structures to provide additional strength, compensate for construction design errors, correct deterioration problems, or improve the performance as required by code changes. These techniques were expensive because of the heavy equipment needed and, in most instances, did not provide a long service life. Corrosion of reinforcement, which is the common deterioration mechanism, affects the life cycle of steel plate in a similar manner. In addition, in certain cases such as strengthening of\u00a0unreinforced masonry<\/strong><\/a> and concrete walls, the traditional techniques cannot be used. High-strength composite materials, used by the aerospace industry for more than 40 years, are becoming the preferred materials for the repairs. Since composite materials are extremely light, the process of installing the composite onto a structure is simplified considerably and, in most cases, heavy equipment is not needed for the repairs. The composites also have very high corrosion resistance. Although the materials are expensive, the final cost of repair becomes competitive because of the ease of construction and the time savings.
