A CASE STUDY ON STRUCTURAL BEHAVIOUR OF BOLTED JOINTS IN GFRP TRANSMISSION LINE TOWERS

Abstract

This thesis deals with the case study on the properties of GFRP (Glass Fiber Reinforced Polymer) In this Thesis we use the GFRP to find out the behaviour of the final product madeby this material which is line transmission tower. Due to the rapid population growth and rapid urbanization, the natural resources are depleting day by day. So, the natural aggregates are very hard to obtain. So many people are opting to use the GFRP (Glass Fiber Reinforced Polymer) instead of the conventional iron or steel channels. The cost of conventional iron or steel channels as compared to GFRP is also very high due to the high demand of it in construction works. GFRP will reduce the quarrying and mining of iron and steel ores thereby reducing the use of natural resources excessively. The land surface can be prevented from any unwanted excavation and hence ecological disturbances will be reduced to conserve the conventional natural iron ore for other important construction works. The compression and the tensile tests are carried out in the thesis to find out the behaviour of the different types of the joints and channel sections with different types of connections. And the result is carried out and accordingly the conclusion is given. This study focuses on the structural behaviour of bolted joints in Glass Fiber Reinforced Polymer (GFRP) transmission line towers, specifically investigating the use of GFRP for these structures as an alternative to traditional steel.
