Hysteretic Behaviour of Shear Stud Connectors in Composite Steel Moment‐Resisting Frames

Dimitrios Lignos, Hammad El Jisr

In steel moment resisting frames (MRFs) with composite floor slabs, seismic loads are transmitted from the slab into the beam through shear studs. Shear strength degradation of the studs due to cyclic loading results into the loss of the load transfer mech ...
