摘要

摘要玻璃纤维增强聚合物（GFRP）用于纵向和横向12根柱，而其他4根柱则使用钢或钢和GFRP作为参考试件进行加固。本文研究了不同荷载条件下的几个参数，如加固材料和拉杆间距。本研究旨在了解GFRP加固柱的承载能力。此外，研究这些柱的失效模式及其在结构中的适用性，因为这些柱是受压构件。试验结果表明，同心加载柱比偏心加载柱具有更高的阻力。此外，与全钢筋和GFRP柱相比，混合柱（钢和GFRP）具有最高的峰值荷载。此外，在相同的荷载条件下，全GFRP RC柱的极限荷载略低于钢柱。

Structural Behavior of GFRP - RC Slender Columns Under Various Eccentricity Loading Conditions

Abstract Glass fibers reinforced polymer (GFRP) were used to longitudinally and transversally 12 columns and while the other 4 columns were reinforced with steel or steel and GFRP as reference specimens. This research dealt with several parameters under different loading conditions, such as the reinforcing material and spacing between ties. This study aims to find out the ability of the reinforced columns with GFRP to bear the loads. In addition, investigate the mode of failure in these columns and their appropriateness in the structures since the columns are compression members. The tested results revealed that the concentric loading columns give higher resistance than their eccentrically loaded counterparts. Also, the hybrid column (steel and GFRP) had the highest peak load compared with the fully reinforced steel and GFRP columns. In addition, the fully GFRP RC- column had an ultimate load slightly less than its steel counterpart under the same loading condition.

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
