Available in PDF, EPUB and Kindle. Book excerpt: The U.S. military must often deploy to other countries where bridges may have insufficient strength for their heavy tactical vehicles. In recent years, fiber-reinforced polymeric (FRP) materials have emerged as a viable retrofit scheme for strengthening reinforced concrete bridges. However, because of stringent application requirements, long cure times, and climatic sensitivity, this technology has yet to prove feasible for military operations where time is often the most critical factor. Furthermore, Army operations are conducted under the broadest range of climatic conditions. For these reasons, the U.S. Army Engineer Research and Development Center has undertaken to develop a unique FRP application methodology utilizing powder-actuated mechanical fasteners (i.e., nails from a conventional carpenter's nail gun). This method shows great promise for military applications, since no substrate preparation or adhesive curing is required. Additionally, this method should work well in all but the most extreme environments. For this purpose, numerous laboratory tests have been conducted, and the results have been very promising. This report provides a detailed summary of the first 2 years of testing on this concept.

Book Synopsis Feasibility of Rehabilitating Timber Bridges with Mechanically Fastened FRP Strips by : Alyssa E. Schorer
Download or read book Feasibility of Rehabilitating Timber Bridges with Mechanically Fastened FRP Strips written by Alyssa E. Schorer. This book was released on 2008. Available in PDF, EPUB and Kindle. Book excerpt: Many timber trestle railroad bridges in Wisconsin have experienced deterioration and are in need of rehabilitation. In addition, the railroad industry is increasing the weights of cars. The combined effect of heavier loads and deterioration threatens to cut short the service life of timber bridges. One of the most critical problems that has been identified was the overloading of timber piles in bridges, which can be remedied by creating a stiffer pile cap. The goal of this investigation was to show that mechanically fastened fiber reinforced polymer (MFFRP) strips fastened to timber with screws can be used to create composite action between two beams in flexure or truss action between two deep beams. Ultimately this may help redistribute the loads to piles when FRP strips are used as struts on cap beams over short spans. Several test series were conducted with beams in flexure, deep beams over short spans, and full scale specimens to determine the manner in which FRP strips improved the members' performance. Tests were conducted over various widths of beams and lengths of spans to investigate how the geometry affected the strengthening's action improved load distribution to piles. Mechanically fastened FRP strips were found to be effective in developing composite action in slender beams in flexure, meaning the stiffness of the system was increased by using MF-FRP strips. This MF-FRP method showed great potential for creating composite, stiffer double pile caps.
