中文译文  使用加固纤维聚合物增强混凝土梁的延性

摘要： 一种为加强结构延性的新型单轴柔软加强质地的聚合物(FRP)已在被研究，开发和生产 (在结构测试的中心在劳伦斯技术大学)。这种织物是两种碳纤维和一种玻璃纤维的混合物，而且经过设计它们在受拉屈服时应变值较低，从而体现出伪延性的性能。通过对八根混凝土梁在弯曲荷载作用下的加固和检测对研制中的织物的效果和延性进行了研究。用现在常用的单向碳纤维薄片、织物和板进行加固的相似梁也进行了检测，以便同用研制中的织物加固梁进行性能上的比较。这种织物经过设计具有和加固梁中的钢筋同时屈服的潜力，从而和未加固梁一样，它也能得到屈服台阶。相对于那些用现在常用的碳纤维加固体系进行加固的梁，这种研制中的织物加固的梁承受更高的屈服荷载，并且有更高的延性指标。这种研制中的织物对加固机制体现出更大的贡献。
