Base plates used in steel column-concrete block connections as one of the most important elements in steel structures can influence thetotal behaviour of structures. Behaviour of base plates as one of the connections that are used in buildings, has its own complexity. Theexistence of different materials such as steel and concrete, interaction between materials, existence of axial force, shear and moment are themost important problems in analysing these connections. In this study, column-base plate connection design procedure of a steel industrialbuilding according to the AISC Base Plate and Anchor Rod Design Guide 1-LRFD method was studied, the column base plate designprocedure was explained for different five load cases. In this study, two dimensional analysis for an industrial building that supports was actas fixed was done in SAP2000 program, then the support reactions that taken from analysis results were used to evaluate column base platedimensions according to AISC-LRFD procedure and details of column base plate connection was checked in ASDIP-steel program accordingto AISC-LRFD. As results, the chosen base plate and footing dimensions and anchor bolts were adequate for the design criteria.

In this study, steel column base plate connections of a steel industrial building that are one of the most important connection regions were studied. Two dimensional static analysis of a steel industrial building was performed and exposed column base plate dimensions were determined according to American Institute of Steel Construction Code-LRFD (Load and Resistance Factor Design) method. The effects of selected steel column cross section types on the behaviour of column base plate connections were investigated by using RFEM finite element analysis program. For this purpose, finite element analysis of three types of column base plate connection models were performed and evaluated comparatively. From results, the best value for top column lateral displacement was obtained in W column section-base plate connection and the best behaviour for Von Mises stresses values was obtained in square hollow section column. The undesired behaviour was determined in circular hollow section column-base plate connection type.
