ABSTRACTEEC-9905711NANNIStructural retrofit and reinforcing work has become important because of the aging buildings and civil infrastructure. Considerable work has been accomplished addressing this problem, but industry is recognizing that more research and development is necessary to directly address the material performance in the field. A planning grant (EEC-9812669) was awarded to the University of Missouri Rolla to determine the feasibility and viability of forming an Industry/University Cooperative Research Center (I/UCRC) for the Repair of Buildings and Bridges with Composites. The Center's research agenda will address: 1). Strengthening of Existing RC Joists with FRP Rods and Sheets, 2.) Strengthening Unreinforced Walls with FRP Material Systems, 3.) Confinement of Rectangular RC Columns Using FRP Jackets, 4.) Bond and Failure Characteristics of Near Surface Mounted FRP Rods, 5.) Anchorage System for Externally Bonded FRP Laminates Using Near Surface Mounted FRP Rods.

由于建筑物老化和民用基础设施的老化，结构改造和加固工作变得非常重要。解决这个问题已经完成了大量工作，但工业界正在认识到，有必要进行更多的研究和开发，以直接解决该领域的材料性能。向密苏里大学罗拉大学颁发了规划补助金(欧洲经济共同体-9812669)，以确定成立工业/大学合作研究中心的可行性和可行性，以便用复合材料修复建筑物和桥梁。该中心的研究议程将涉及：1)。用玻璃钢棒和片材加固现有的钢筋混凝土托梁，2.用FRP材料体系加固无筋墙体，3.使用FRP夹套的矩形钢筋混凝土柱的约束，4。近表面贴装玻璃钢棒的粘结与破坏特征使用近表面贴装玻璃钢棒的外粘合玻璃钢层合板的锚固系统。
