Abstract
This paper describes an experimental program developed to investigate non-bearing spliced composite short column connections made of Glass Fiber Reinforced Polymer (GFRP) that are subjected to axial loading. This study provides aspects such as the load-bearing capacity of the connection, failure modes, load distribution in the connection, displacement in the joint, stiffness, and compressive strength. The design of the joint in this study that connects two 350mm GFRP H-sections to form a short column connection is based on euro codes BS EN 1990 and BS EN 1991, which are used to design steel splicing connections for beams and columns. Four design specifications models are made depending on the positioning of the cover plates in the inner flange, outer flange, and web region of the H-sections to examine the requirement of a specific cover plate, and the H-sections are bolted to each other using M8 8.8 grade steel bolts. The samples tested in this study indicated a dominant failure in the flange region, with model-4 providing 92.83% compressive strength when compared to an uncut GFRP short column.
本文介绍了一种研究受轴向载荷作用下玻璃纤维增强聚合物(GFRP)非承重拼接复合短柱连接的实验程序。该研究提供了连接的承载能力、破坏模式、连接中的荷载分布、节点中的位移、刚度和抗压强度等方面的信息。本研究中两个350mm玻璃钢h型钢截面连接形成短柱连接的节点设计，依据欧洲规范BS EN 1990和BS EN 1991进行梁柱拼接连接设计。根据盖板在h型钢内法兰、外法兰、腹板区域的定位，制作四种设计规范模型，考察某一特定盖板的要求，h型钢采用M8 8.8级钢螺栓相互紧固。在本研究中测试的样品表明，主要破坏在法兰区域，与未切割的GFRP短柱相比，模型4提供了92.83%的抗压强度。
期刊介绍：
Engineering Solid Mechanics (ESM) is an online international journal for publishing high quality peer reviewed papers in the field of theoretical and applied solid mechanics. The primary focus is to exchange ideas about investigating behavior and properties of engineering materials (such as metals, composites, ceramics, polymers, FGMs, rocks and concretes, asphalt mixtures, bio and nano materials) and their mechanical characterization (including strength and deformation behavior, fatigue and fracture, stress measurements, etc.) through experimental, theoretical and numerical research studies. Researchers and practitioners (from deferent areas such as mechanical and manufacturing, aerospace, railway, bio-mechanics, civil and mining, materials and metallurgy, oil, gas and petroleum industries, pipeline, marine and offshore sectors) are encouraged to submit their original, unpublished contributions.
