In order to examine behavior of an exposed-type column base of steel structures with simplified vertical anchor reinforcement, cantilever beam-columns with RC footing beam are tested under cyclic horizontal force. The test parameter is axial force, strength of anchor bolts and direction of horizontal force. Based on the test results, strength and stiffness of the exposed-type column base are discussed. And it is shown that previous design formulas about those are effective for column base with simplified vertical reinforcement.
