Mechanics Characteristics of Concrete Beams Reinforced with Continuous Fiber Rope

SupervisorFTakumi SHIMOMURA

Continuous fiber materials in many different types such as rods, grids, sheets, etc. have been widely used in concrete structures for their obvious advantages, namely high strength, high durability, and lightweight. These continuous fiber materials are compounded with the epoxy resin. In this study, a new type of continuous fiber material made in the form of rope, hereafter Continuous Fiber Rope (CF Rope), has been investigated. CF Rope is enough flexible to be easily arranged in structural members by hand , it is considered to be used without epoxy resin.
In this study, the experiment was carried out for four specimens, which were changed the arrangement of shear reinforcement. Through the experiments, the failure behaviors of the beams were discussed and the shear strengthening effectiveness of CF Rope was evaluated. Also material tests were carried out to determine the mechanical properties of CF Rope.
The results are shown below
(1)The gripping system that was consisted of steel tubes filled with expansive grout was used. Tensile strength was measured in sufficient accuracy, when the section of CF Rope inside the anchoring section was strengthening by epoxy resin.
(2)It was confirmed that CF Rope can be used effectively as shear reinforcement for concrete beams.
