Abstract:Reinforced concrete columns are the main load-bearing component of the structure. In order to en- hance more efficiently the seismic behavior of reinforced concrete columns, a method to strengthen column by using different height of cement-based grouting material with steel wire mesh (CGMM)was proposed. Three rein- forced concrete columns were tested under low reversed cyclic loading and the process of tests was introduced. Failure mechanism, hysteretic behavior, ductility, cumulative energy dissipation and stiffness degradation of specimens were analyzed. The experimental results showed that the seismic performances of CPRP1 and CPRP2 specimens were significantly higher than that of CP specimen. In the columns of different strengthened height, with the increase of CGMM strengthened layer, the peak load, ductility and energy dissipation of specimen in- creased and the stiffness degradation became less rapid.
