摘要

摘要:由于FRP筋具有较低的弹性模量和弹脆特性，挠度控制设计是FRP筋构件设计的关键部分。本文概述了挠曲控制的设计，包括对梁挠曲的基本力学的简要回顾，以及对开裂、拉伸加劲、收缩和蠕变的计算方法的回顾。本文还讨论了选择合适的挠度控制准则的基础，并提出了将挠度控制纳入整体设计过程的框架。

Deflection Control for FRP-Reinforced Concrete Members: An Overview

Synopsis: Design for deflection control is a critical part of the design of FRP reinforced members due to the relatively low modulus of elasticity and elastic-brittle nature of FRP reinforcement. This paper provides an overview of design for deflection control including a brief review of the basic mechanics of beam flexure and a review of methods to account for cracking, tension stiffening, shrinkage and creep. The basis for selecting appropriate deflection control criteria is also discussed and a framework is presented to incorporate deflection control into the overall design process.
