摘要：
An extensive parametric study on stable limit axial force of exposed-type column base of concrete filled steel tube (CFT) was carried out using an elasto-plastic analysis which was proposed by the authors. In the analysis, force-deformation relationships of anchor bolt, base plate, and concrete in the connection panel of a column base were taken into account. Analytical results indicated that exposed-type CFT column bases showed stable behavior even under high axial force. The effects of material strength, shape of base plate, dimension of column, and lateral reinforcement ratio of connection panel on stable limit axial force of exposed-type CFT column base are discussed.
