To investigate the seismic behavior of RC columns strengthened with textile reinforced concrete (TRC) added PVA fiber, seven reinforced concrete (RC) columns were designed, one of which was used as the control column, (Four of the columns were square, one was circular, and the rest were rectangular.) and six of which were strengthened with TRC. The lowfrequency cyclic loading test was conducted by considering the volume quantities of PVA fiber and section forms of columns. The experimental results show that TRC can constraint the core area of concrete, restrict the development of concrete cracks effectively by adding a moderate PVA fiber, and the cracking loads and peak loads of the columns increase. When the volume quantities are within 0.5%, the ductility of the strengthened columns is improved, the stiffness degradation rate is small, and the energy dissipation increases. With the increase in volume quantities, the strengthened columns perform poorly in ductility, energy dissipation, and stiffness degradation. The circular column strengthened with TRC has a low bearing capacity, but it is superior to other cross section columns in ductility, stiffness degradation, and energy dissipation. The reasonable volume of PVA fiber should be less than 0.5%, and the strengthened circular column performs better in seismic behavior.
