Bolted T-stub Macro-components Under Combined Cyclic and Monotonic Loading
End plate bolted joints are frequently used in seismic resistant multi-story steel frame structures. Their flexural behavior can range from flexible and partial strength to stiff and full strength. For partial strength joints, the main source of ductility is the T-stub macro-component. While most studies and design provisions envisaged the response under single critical events, e.g., strong earthquakes, experience shown they may be vulnerable in a multi-hazard environment, e.g., earthquake aftershock, or column loss (due to fire or explosion) after earthquake.
The study presents the results obtained on a set of T-stub elements subjected to monotonic and cyclic loading, single or in sequence monotonic after cyclic. The influence of several parameters including the loading protocol and plastic deformation demands, are also investigated. Numerical models are calibrated against test data.
