POWRE: Enhancement of Beam-Column Connections Through the Use of Fiber Reinforced Plastic

这项研究涉及到将复合材料，如纤维增强塑料（FRP）到钢筋混凝土梁柱连接加固/康复的目的。 与钢相比，FRP材料具有几个优点，包括重量轻、耐腐蚀性以及将FRP覆盖层模制到混凝土表面的能力。 玻璃钢产品可用于初期施工或结构修复/增强。 FRP覆盖层加固的使用并不新鲜，其在混凝土中的应用也不新鲜。 新的是将这种技术应用于结构连接。 本研究的目的是确定合适的配置环氧树脂粘结FRP覆盖层，以获得在梁柱连接的弯矩传递。 本研究将集中于框架的外部接头。 本研究将使用分析建模和实验室测试的缩小模型，研究各种配置的环氧树脂粘结FRP覆盖层的能力，以增加梁-柱节点的抗弯承载力。

This research involves the incorporation of composite materials such as fiber reinforced plastic (FRP) into reinforced concrete beam-column connections for strengthening/rehabilitation purposes. FRP materials have several advantages over steel including, light weight, corrosion resistance, and the ability to mold FRP overlays to concrete surfaces. The FRP products can be used in the initial construction or for structural repair/enhancement. The use of FRP overlay reinforcement is not new, nor is its application to concrete. What is new is the application of this technology to structural joints. The objective of this research is to determine appropriate configurations of epoxy bonded FRP overlays to obtain moment transfer at beam-column connections. This investigation will concentrate on an exterior joint of a frame. This research will use analytical modeling and laboratory testing of scaled down models to study the ability of various configurations of epoxy bonded FRP overlays to increase the flexural capacity of a beam-column joint.
