“…Anchors that function flawlessly in monotonic tensile tests are often required to be modified for cyclic loading. El Refai [1] and Noël & Soudki [2] used modified reusable anchorage system. Its advantage is the possibility of re-use without the need to glue the bar to the anchor.…”

The paper describes an experimental program for studying the fatigue performance of GFRP bars, which has been initiated by the authors. Two different test configurations were used to assess the fatigue behaviour. The bare specimens were tested within the first series. A modified gripping system was used to reduce eccentricity when the bar was not directly fixed. However, the boundary conditions seem to affect the results. The second series consisted of a set of specimens of bars embedded in concrete. This configuration seems appropriate for determination of fatigue life of GFRP bars. Two S-N curves for bare bars and bars embedded in concrete were created and compared. Significant reduction of interlaminar shear strength at the beginning of fatigue loading proved matrix or fibre/matrix interface damage.

“…Its advantage is the possibility of re-use without the need to glue the bar to the anchor. However, during the cyclic loading, there is slipping of the bar in the anchor, which can be in the order of millimetres, [1]. Concrete blocks for reinforcement anchoring were used in experiments by Adimi [3], Rahman [4] and Benmokrane [5].…”

“…A similar comparison is made in [11][12][13] and it is shown that the tensile, bending and shear strength limits and modulus of elasticity are not inferior to GRP in their resistance. In [14][15][16] the resistance of basalt-plastic materials to low, high temperatures and thermocycles has been investigated and the stability of these materials to the specified effects has been shown. In works [17,18] similar conclusions about high stability of BPA to influence of aggressive environments are received after estimation of influence of water, saline and alkaline solutions at normal and raised temperatures on mechanical properties of rods in diameter of 11-12 mm.…”

This paper presents the data of changes in the coefficient of thermal expansion of composite reinforcement and heavy concrete in a wide temperature range. Studies allow not only to justify the high stability of the BPA in terms of thermal expansion, but also to assess the subtle effects of measured parameters for parallel samples in the initial state and after climatic tests in Yakutsk. We identified the optimum relations of heavy concrete with limestone rubble of 60 % and gabbro-dolerite-40 %, providing high degree of compatibility of temperature expansion with composite armature, for increase of crack resistance and excluding crack formation at temperature changes. The results allow to determine the optimal formulation of concrete reinforced with composite reinforcement for their possible use in the creation of new structural materials.

Flexural fatigue behavior of a pultruded basalt fiber reinforced epoxy plate subjected to elevated temperatures exposure

In the present article, effects of elevated temperature treatment on the flexural fatigue behavior of a pultruded basalt fiber reinforced epoxy plates (BFRPs) were investigated. Elevated temperature treatment conditions were set as 150 and 2508C for 0.5, 1, and 2 h in an oven. The static testing results revealed that elevated temperature treatment only brings in slight degradation in the flexural properties of the BFRP. However, the short beam shear strength (SBS) was deteriorated significantly. Dynamic mechanical thermal analysis (DMTA) results indicates that elevated temperature treatment at 1508C mainly shows a post-curing effect on the resin matrix, while elevated temperature treatment at 2508C leads to fiber debonding and decomposition of the resin. The S-N curves of BFRP (untreated and treated 150 and 2508C for 1 h) show that the elevated temperature treatment decreased the fatigue lives of BFRP remarkably, especially under high strain ratio. As indicated, elevated temperature treatment accelerates the growth of the damages due, mainly, to the deteriorated fiber-resin bonding property and increased void content. POLYM.
