Abstract

Column base have a inportant role that transmit a load which impat to structure to base in steel structure. The column bases behave with a compressive force, shear force and bending moment, particularly moment-rotation behavior which has occur by bending moment have a effect to a horizontal deformation of framework and column safety so it have a inportant roll for analysis of entire structure as non-linear behavior. Exposed column is consist of base, anchor bolt, base plate and column and it show so complicated behavior that structural behavior need to clearly define as safety of entire structure. although non-linear behavior of column bases demand enough experimental study and theoretical analysis like this, it is a lack of research compare with beam-column connet. Therefore. in this study, analysis that column bases by modeling using a general finite element analysis program and reviewing a validity compare with existing research result, it have an objet in view that structural behavior characteristics of exposed column bases by thickness of base plate, yielding stress ratio of base plate and anchor bolt which is very important element of behavior of column bases.
