要旨	The behavior of six reinforced concrete columns subjected to unidirectional cyclic lateral loading with constant and variable axial loads, and their experimental results are presented. Four specimens were tested under constant axial loads and two specimens under variable ones. Two types of concrete strength and two types of lateral reinforcement ratio were used. Failure modes, cracking patterns and ductility levels are discussed. The results indicated the influence of the variation of axial forces and their magnitudes on lateral strength, stiffness and deformation characteristics of the columns.
