A yielding criterion for seismic gusset plates in tension

Conference Paper


Abstract


  • Gusset plate yielding has been recognised as a complementary ductile yielding mechanism in the balanced design procedure proposed for special concentrically braced frames (SCBF). The procedure aims to maximise the frame’s drift capacity. To achieve the aim, accurate models for determining the yield resistance of relevant components is desirable. Thicker than necessary gusset plates have been found to limit the drift capacity. Based on the authors’ previous finding regarding the Whitmore tension resistance of bolted connections, this paper proposes a more rational yielding criterion for bolted gusset plates in tension. The proposed block shear yielding criterion not only facilitates the application of the balanced design procedure to SCBF with bolted braces in tension, but also ensures a reliable ductile yielding mechanism.
