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

本研究涉及将纤维增强塑料（FRP）等复合材料掺入钢筋混凝土梁柱连接中，用于加固/修复目的。玻璃钢材料比钢有几个优点，包括重量轻，耐腐蚀，以及将玻璃钢覆盖在混凝土表面的能力。FRP产品可用于初始施工或结构修复/增强。玻璃钢加筋的使用并不新鲜，也不是它在混凝土中的应用。新颖之处在于该技术在结构缝中的应用。本研究的目的是确定环氧树脂粘结玻璃钢覆盖层的适当配置，以获得梁柱连接处的力矩传递。这次调查将集中在一个框架的外部连接。本研究将使用分析模型和按比例缩小模型的实验室测试来研究环氧树脂粘结FRP覆盖层的各种配置增加梁柱节点的抗弯能力的能力。

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.
