STRENGTHENING SQUARE CONCRETE COLUMN WITH BASALT FIBRE TEXTILE REINFORCED ECC
Confining concrete elements with fibre reinforced polymer(FRP)is proven to be an efficient technique in improving the dilation and axial performance of concrete columns.However,its effectiveness is reduced significantly for non-circular columns.In addition,a few drawbacks of using FRP,such as brittleness of FRP sheet and poor performance of the material at high temperatures,have been found in recently year.This paper presents a feasibility investigation of a newly developed strengthening system,basalt fibre textile reinforced engineered cementitious composite(ECC).Three types of basalt continuous fibre grid were used,in combination with ECC to confine non-circular concrete columns.The experimental results revealed that the new strengthening system has significantly enhanced the load carrying capacity and ductility of non-circular concrete columns compared to the unconfined specimens and the textile reinforced mortars(TRM)technique.The results also shown that ECC itself could be used as a new retrofitting material in column confinement.
