Seismic performance of steel moment frames with side-plate connections has been investigated with emphasis put on earthquake uncertainties. Based on experimental and finite element results, a connection model was proposed and calibrated to represent the side-plate connection behavior. Afterwards, some two-dimensional moment frames were adopted from the designed three-dimensional frame structures which were modeled incorporating the established connection model. To reflect the uncertainties associated with earthquakes, the incremental dynamic analysis procedure was performed. The procedure outcomes, which consist of more than 1500 nonlinear dynamic analyzes, were used to investigate the structures performance in terms such “limit-state frequencies” and “seismic demand hazard curve”. The quantified performances may be used in comparing the studied structures with similar other structures and also as a crisis to the prescriptions issued by design guidelines for the structures under consideration.
