New Component-Based Model for Single Plate Shear Connections with Pretension and Pinched Hysteresis



Jonathan M. Weigand


The behavior of single plate shear connections under extreme loads is complex. However, component-based connection models provide a natural framework for modeling these complexities, by capturing both the individual behaviors of the connection components, such as the bolt, shear plate, and beam web, and the complex interactions between those components. Component-based models also provide automatic coupling between the in-plane flexural and axial connection behaviors, a feature that is essential for modeling the behavior of connections under column removal. This paper presents a new component-based model for single plate shear connections, that includes the effects of pretension in the bolts and provides the capability to model standard and slotted holes. The component-based models are exercised under component-level deformations calculated from the connection demands via a practical rigid-body displacement model, so that the results of the presented modeling approach remains hand-calculable. Validation cases are presented for connections subjected to both seismic and column removal loading. These validation cases show that the component-based model is capable of predicting the response of single plate shear connections for both seismic and column removal loads.
