چکیده مقاله
Fixity of column base connection plays a major role in overall behavior of steel structures Although it is usually idealized as fully pinned or fully rigid, in reality it often exhibits semi rigid behavior The currentstudy investigates the nonlinear behavior of regular column base connection and assesses its partial fixity Therefore, results from analyses of several steel frames modeled with pinned or fixed ends were utilized to design column base connection Respectively each connection was modeled by nonlinear finite element method to obtain the relative rigidity of each set of connection Then, corresponding effects have beenapplied to steel frames to investigate semi rigidity effects on overall structural responses The results clearly indicate that regular column base connection behaves in a semi rigid manner It is shown that in cases where the column bases are classified as pinned, they often have significant rotational stiffness Meanwhile, assumedly rigid connections may exhibit considerable rotation
