Abstract
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.
Highlights
The column base plate connections are one of the most important regions of steel structures
Steel column base plates have a great importance of whole structural behaviour, these connections are responsible of transferring the loads from structures to the foundations
The column base plate connection of the industrial building was found under large moment effect according to the American Institute of Steel Construction (AISC) Base Plate Design Guide 1
Summary
The column base plate connections are one of the most important regions of steel structures. The best way of studying the behaviour of column base plate connections was testing experimental models. Understanding the behaviour of different types of base plates, failure modes and their advantages and disadvantages by using computer simulations can result in great savings. The relation between experimental and analytical model of column base plates was shown in many studies. Most of these investigations were on simple base plates without stiffeners and the verification among results seemed to be satisfactory (Shafieifar & Khonsari, 2012, Stamatopulos & Ermopoulos, 2011). Nonlinear finite element analysis for a single story steel industrial building with exposed column base plate connections having different column types were performed. The finite element analysis of these types of steel column base plate connections were performed and evaluated comparatively
