Application of FRP Strap in an Innovative Prestressed Method
Publication: Journal of Materials in Civil Engineering
Volume 21, Issue 4
Abstract
Fiber-reinforced polymer (FRP) strap is one of the FRP forms. Its width is small and its thickness is large. The wave-shaped-gear-grip anchorage (WSGG) was developed specifically for the FRP strap. A brand-new method has been developed for externally anchored FRP sheet prestress strengthening, which makes full use of the features of WSGG anchors by fixing both ends and then fastening the middle to force FRP sheets to elongate geometrically and generate a pretension. Worn bridge members (solid RC plates of long) removed from the Cheng-Yu Expressway were used in this experiment of externally anchored CFRP strap prestressed strengthening. The experiment results demonstrated that the proposed method for the application of prestressing FRP straps is very simple, easy, and technically practical, and can significantly enhance the effectiveness of strengthening. It was also shown that the proposed method will have broad applications.
