Testing and Evaluation of Buckling and Tensile Performance of Glass Fiber–Reinforced Polymer Angle Section with Different Joints/Connections

Abstract

The aim of this paper is to investigate the crushing and tensile performance of built-up glass fiber–reinforced polymer (GFRP) pultruded angle sections under compression and tension loads. For the compression test, two GFRP angle sections of size 50 × 50 × 6 mm were selected and maintained the e/d ratio of 5. GFRP angle sections were connected by two-bolt, three-bolt, four-bolt, adhesive, hybrid two-bolt, hybrid three-bolt, and hybrid four-bolt connections. For the tension test, single-lap joint and single-bolt connections were considered. The tension test is performed by angle-to-angle connection with an e/d ratio of 5. Also, the joints were connected by single-bolt connection, hybrid single-bolt with local glue, and hybrid single-bolt with epoxy connection. Based on the studies, the best joint and connection were considered, and a transmission line tower with various connections is modeled and proposed using ANSYS.
