Hollow Concrete Poles with Polymeric Composite Reinforcement

N. Taranu, G. Oprisan, M. Budescu and I. Gosav

The results of a theoretical and experimental study carried out on the possibility of using polymer composite reinforcing elements for a power supply hollow Reinforced Concrete (RC) column are presented in the study. The composite reinforcing elements are utilized both as longitudinal glass reinforced thermosetting polymer (vinylester) bars and transverse reinforcement made of a Glass Fibre Reinforced Polypropylene (GFPP) spiral. The columns have been fabricated using the existing manufacture facilities based on centrifuge procedure. An experimental program has been organized to evaluate the structural response of spun-cast elements according to existing standard tests. A number of loading cycles of lateral action have been applied on the posts up to failure. Cracks development and the corresponding loading stages have been recorded. A theoretical analysis has been performed to prove the suitability of existing calculation formulas for serviceability and ultimate limit states. This study confirms the possibility of using composite reinforcement for hollow tapered RC columns.
