Abstrakty
EN Basalt fiber-reinforced polymer (BFRP) bars are a new material used in reinforced concrete (RC) structures. They present such properties as high tensile strength, low modulus of elasticity and shear strength. Due to these mechanical properties, flexural behavior of BFRP RC elements is significantly different to that of traditional steel RC. This paper presents the results of an experimental and theoretical study of the short-term flexural behaviour of a series of simply supported BFRP RC beams. The beams were tested under four-point bending. The main objective of this paper was to investigate deflections of the beams depending on reinforcement ratio. The results of experiments were compared with code formulations and prediction models.
PL Bazaltowe pręty zbrojeniowe (BFRP) są stosunkowo nowym materiałem stosowanym w budownictwie. Charakteryzują się one wysoką wytrzymałością na rozciąganie, niskim modułem sprężystości oraz niską wytrzymałością na ścinanie. W artykule przedstawiono wyniki badań laboratoryjnych zachowania się belek zbrojonych prętami BFRP poddanych działaniu obciążenia statycznego. Głównym celem badań było określenie wpływu stopnia zbrojenia na ugięcia zginanych elementów. Rezultaty badań porównano z wynikami obliczeń teoretycznych.
