This study investigates the behavior of Partially Restrained (PR) connections with high strength steel through the use of Finite Element (FE) modeling. The connection model is such that double web angles are represented by radiused corner section shell elements. The full interaction between the angle and the beam and/or column is simulated by the contact element.The analysis of the moment- rotation relationship and behavior characteristics of the connection with high strength steel are compared and discussed. It is established that the contact elements and strength enhancements of the corner regions employed in this model are important parameters for accurate predictions of Double Web Angle (DWA) connection behavior with cold-formed high strength steel. The proposed connection FE model is capable making highly accurate predictions about the ultimate load capacity and the plastic strain pattern. The model presented provides excellent results for significantly increasing the connection capacity as a result of employing a higher strength steel section. A power model expression was proposed to predict the ultimate moment and initial stiffness of the high strength DWA connection. A reasonable prediction was obtained for high strength PR connection.
Key words: Cold-formed, high strength steel, moment capacity, partially restrained, radiused corner, web angle,
