Static Response of Fiberglass Pretensioned Columns
Publication: Journal of Structural Engineering
Volume 120, Issue 12
Abstract
Six pretensioned concrete columns, either with fiberglass or steel tendons, long, were tested to failure under axial and eccentric loading. Four were fiberglass pretensioned columns, two with steel square spirals and two with fiberglass square spirals. For comparison, two identical steel pretensioned columns were also tested. The fiberglass tendons were made of S‐2 glass/epoxy, and the fiberglass spirals of E‐glass/epoxy. The slenderness ratio for the pretensioned columns was 40, and the eccentricity ratio 0.25. The columns were instrumented to measure strains in the concrete, prestressing strands, and lateral deflections at midheight. The results of the tests revealed that the performance of the fiberglass and steel pretensioned columns was very similar, although the confinement provided by the fiberglass spirals was inferior to that of steel. The test results also showed reasonable agreement with nonlinear finite‐element analyses using the PCFRAME program.
