Ductile Behavior

Six concrete piles reinforced with 500MPa fine-grain steel bars were tested under low cycle reversed loading to study the seismic behavior such as failure patterns, characteristics of hysteretic and skeleton curve. Three parameters, longitudinal reinforcement strength, reinforcement ratio and axial compression ratio were taken into consideration. The main failure patterns as well as hysteretic curve of those piles were obtained, and influence of each of the three parameters on the ductile behavior, ability of energy dissipation and law of strength degeneration were analyzed. The experimental results indicate that the mechanical behavior of reinforced concrete low cyclic reversed loading columns with fine grain high strength reinforcement is similar to normal reinforced columns. The concrete piles reinforced with 500MPa fine-grain steel bars show good seismic performance and 500MPa fine-grain steel bars can be used in seismic design.
