Analysis of Green House Systems Using Fiber Reinforced Polymer Cables

Abstract

This thesis presents a biconcave cable truss as a roofing system for green houses by using non-traditional cable materials. Not only traditional steel cables were used but also FRP cables namely: high-strength carbon FRP (CFRP), hybrid FRP cables such as basalt mixed with carbon with two different volume proportions 25% and 50% of carbon fiber called B/CFRP 25% and B/CFRP 50%, respectively. Also, another newly developed hybrid FRP cable formed by the hybridization of basalt and steel cables together with two volume proportions 20% and 30% called B/SFRP 20% and B/SFRP 30%, respectively. These hybrid cables have been tested for large scale cable stayed bridges and were deemed appropriate. Up to the author’s knowledge using FRP cables in cable trusses as roofing structure has never been studied. Several parameters have been tested in this study to get a better understanding of the cable truss behavior.
