Abstract: The local buckling restraining behavior of thin-walled circular concrete-filled tubular (CFT) columns is examined under seismic loads by conducting a bidirectional cyclic loading and a bidirectional shaking table test. ...

Abstract: To check the safety of thin-walled circular steel columns used for bridge piers of elevated-girder bridges, a versatile interaction equation is derived to specify the ultimate state of the columns under the coupling of ...
