Abstract:The application of fiber reinforced polymer (FRP) materials in foundational establishment is a growing field in the world. The authors have investigated a series of FRP materials and application techniques in foundational establishment construction field based on “The National Advanced Materials Committee of China” foundation item (2001AA336010). Properties of FRP materials have been improved by experimental and analysis on hybrid of two or three kinds of fiber, and various products have been manufactured accordingly. At the same time, the resin and equipment that are suitable for those FRP materials have been developed. A series of key applied techniques, such as strengthening of steel structures, masonry structures and concrete structures reinforced with prestressed FRP, lossless inspectability of structures and so on, have been developed though experimental research according to requests of engineering. There are four codes and guidelines for applying FRP techniques to construct foundational establishment. Among them, one technical specification was published in May 2003. It can be standardization of applying FRP materials on engineering. There have been more than one hundred engineerings strengthened with FRP materials since 1999 based on research and investigation of FRP materials and techniques. There is a huge advance to use FRP on foundational establishment of society in China.
