Failure behavior of a top and seat angle bolted steel connection with double web angles Failure behavior of a top and seat angle bolted steel connection with double web angles Peer-Reviewed Journal Publication Δημοσίευση σε Περιοδικό με Κριτές 2015-10-122015enThe article presents a three-dimensional nonlinear finite-element model that was developed for the study of a top and seat angle bolted steel connection with double web angles. Unilateral contact and friction laws were used to simulate the interaction among the connected parts. Large displacements as well as the von Mises failure criterion were also considered for the steel parts and bolts. Numerical results were compared with the experimental research conducted on the same steel joint. This study finds yielding of the top angle as well as shear failure of the bolts connecting the beam bottom flange with the seat angle to be very important for the overall response of the structure. For this reason, a parametric investigation of the influence of the top angle on the behavior of the structure and the study of the prying forces developed at the top angle were conducted. http://creativecommons.org/licenses/by/4.0/Journal of Structural Engineering7141 Stavroulakis Georgios Σταυρουλακης Γεωργιος Drosopoulos Georgios Δροσοπουλος Γεωργιος K.Abdalla Applied mechanics Engineering, Mechanical mechanics applied applied mechanics engineering mechanical
