Abstract

Structural poles carrying lighting fixtures and traffic signs as well as those supporting power and communication lines are traditionally made of timber, metals and steel-reinforced concrete. However, corrosion and aging problems deteriorate their structural integrity and architectural appearance. Recently, the tubes made of Fibre Reinforced Polymers (FRP) with their non-corrosive nature and high strength to weight ratio have been a favourable option for structural poles. Yet, the background about their structural behaviour, in general, and their performance under seismic conditions, in particular, is quite limited. Therefore, the present paper throws the light on a study that investigates the dynamic behaviour and seismic response of Glass GFRP structural poles in high seismic zones. Various parameters have been considered such as the height of the pole mast, the length of the pole arm and the weight of the pole fixture(s). The influence of these parameters on the pole dynamic characteristics as well as on the seismic straining actions induced at the pole base has been investigated. Further, the study results present an approach towards optimising the design of FRP structural poles subject to severe earthquake condition.
