Reinforced concrete structures in service are usually with cracks and subjected to the service load,the hysteretic behavior of reinforced concrete structures with sustained eccentric loads and cracks needs to be investigated.The 28 d cured reinforced concrete columns with different sustained compressive eccentric loads were cured in the nature condition for 100 d,then their hysteretic behaviors were tested after the sustained loads were removed.Results showed that when the horizontal load produced the same tensile and compressive stress distribution as that of sustained eccentric load,the ultimate loads,ductility and initial stiffness of columns decreased with the increase of sustained eccentric loads.When the horizontal load was reverse,the ultimate loads showed an descend trend,while the initial stiffness and ductility increased with increase of sustained eccentric loads.The sustained eccentric loads had an impact on the hysteretic behavior of reinforced concrete columns.
