Abstract

Prestressing of the fiber-reinforced polymer (FRP) plate is applied to fully extend the high-strength performance of the FRP plate in structure reinforcement. Anchoring methods and stressing are the two main issues for prestressed FRP plates. Although a number of methods concerning those two main issues have been developed, the literature lacks a systematic review on the existing methods for FRP plates anchoring and stressing. This article compares the comprehensive performance of different FRP plates, recommending BFRP plates as more suitable for use in prestressed tensioning systems. It contrasts the principles and applicability of various anchoring devices, suggesting that wedge-type clip anchors and flat-type anchors show promising development prospects. Additionally, addressing stress concentration in the anchorage zones of low-modulus FRP plates is key to enhancing anchoring efficiency. Ultimately, the paper evaluates tensioning methods for FRP plates, identifying “the method of jacking against the strengthened component” as the most promising, yet it requires innovation in terms of dimensions and positioning of the tensioning frame to enhance its applicability to specific engineering needs.

预应力玻璃钢板的锚固和受力方法：最新技术回顾

对纤维增强聚合物（FRP）板施加预应力，可充分发挥 FRP 板在结构加固中的高强度性能。锚固方法和应力是预应力玻璃钢板的两个主要问题。虽然针对这两个主要问题已经开发出了许多方法，但文献中缺乏对现有玻璃钢板锚固和应力方法的系统综述。本文比较了不同玻璃钢板材的综合性能，推荐 BFRP 板材更适合用于预应力张拉系统。文章对比了各种锚固装置的原理和适用性，认为楔形夹板锚固和扁平锚固具有广阔的发展前景。此外，解决低模量玻璃钢板锚固区的应力集中问题是提高锚固效率的关键。最后，论文对玻璃钢板的张拉方法进行了评估，认为 "顶住加固部件的方法 "最有前途，但需要在张拉框架的尺寸和定位方面进行创新，以提高其对特定工程需求的适用性。

期刊介绍： The Journal of Reinforced Plastics and Composites is a fully peer-reviewed international journal that publishes original research and review articles on a broad range of today''s reinforced plastics and composites including areas in: Constituent materials: matrix materials, reinforcements and coatings. Properties and performance: The results of testing, predictive models, and in-service evaluation of a wide range of materials are published, providing the reader with extensive properties data for reference. Analysis and design: Frequency reports on these subjects inform the reader of analytical techniques, design processes and the many design options available in materials composition. Processing and fabrication: There is increased interest among materials engineers in cost-effective processing. Applications: Reports on new materials R&D are often related to the service requirements of specific application areas, such as automotive, marine, construction and aviation. Reports on special topics are regularly included such as recycling, environmental effects, novel materials, computer-aided design, predictive modelling, and "smart" composite materials. "The articles in the Journal of Reinforced Plastics and Products are must reading for engineers in industry and for researchers working on leading edge problems" Professor Emeritus Stephen W Tsai National Sun Yat-sen University, Taiwan This journal is a member of the Committee on Publication Ethics (COPE).
