The behavior of shear studs affect load transfer between the steel girder and the concrete deck. This aspect of behavior has vital importance in the evaluation of redundancy for composite steel bridges with fracture critical members (FCMs) in which the fracture of a member is being evaluated. It is important to include proper shear stud properties which cover the shear, tensile, and combined shear and tensile behavior to prevent erroneous conclusions when evaluating the redundancy of such bridges. In this study, a shear stud damage methodology was developed by calibrating finite element (FE) analysis to existing experimental data and other methodologies. The numerical results from FE models were used to develop new modification factors for the existing methodologies and develop an approach to more accurately model the strength, stiffiness, and ductility of stud damage behavior for a range of typical shear stud, haunch, and flange configurations. Keywords: concrete breakout; finite element (FE); haunch; shear stud; tensile.
INTRODUCTION For steel-concrete composite bridges, shear studs are critical to the load transfer between the steel girder and concrete deck as they help provide additional load paths after a primary [...]
