Performance Characterization of Hybrid Composite Reinforcement in Short Column
The new reinforcement material, Hybrid Composite, is new innovative material.The new Hybrid Composite (HC) reinforcement is made of carbon fiber or other fibers in the form of tubular weave or braid.HC tubes possess corrosion resistance, lightweight, high strength, and good ductility.Carbon fiber has been used in civil engineering applications, especially in column and pier.Carbon fiber sheets are wrapped around concrete columns to restrict the lateral expansion of concrete to improve the compression performance, while protecting the column as well.In this paper, the performance characterization of HC reinforced concrete short columns subjected to compression loading is analyzed.By testing the model and analysis the result, the strain, displacement, and load capacity of all specimens are collected and analyzed in terms of the number of HC layers and eccentricity ratios.The results show that the ultimate load capacity of columns increases with the number of HC layers under axial compression;the ductility and load reduction after exceeding the peak loads are reduced with the increasing the numbers of HC layers.Compared with plain concrete columns, HC reinforcement significantly improves the ductility of the reinforced columns.Under eccentric compression, the ultimate load capacity decreases with the increase of eccentricity ratio, but the reductions in load capacity decrease gradually under the same numbers HC layers.This confirms the superiority of the HC reinforcement.
