Abstract

Abstract

In the specifications on detailing of stirrups and minimum hoop characteristic factors in column hoop densified regions,there exists large difference between Chinese Codes and related codes of other countries.So it is necessary to check the seismic behaviors of columns with different transverse reinforcement schemes in different codes.Moreover,it is needed to verify the seismic behaviors of columns designed to Chinese Codes using HRB500 rebars with a higher strength as longitudinal reinforcements.Reverse cyclic loading tests of 9 RC column specimens reinforced with HRB500 rebars were conducted.The test parameters included the transverse reinforcement ratio,hoop characteristic value,stirrup strength and arrangement of stirrups.The effects of these parameters on the failure mechanism,load-deflection hysteretic-curve,ductility,stiffness degradation and energy-dissipating capacity were analyzed.Different behaviors between the columns with HRB500 rebars and those with HRB335 rebars were discussed,with other parameters remaining the same.The results showed that when the details of stirrups in hoop densified regions confirming to the design codes,the columns reinforced with HRB500 rebars could meet the seismic requirements of deformability and ductility.
- reinforced concrete column,
- HRB500 rebar,
