This research studies the performance of two- and four-story steel building models against progressive collapse in two cases: (1) skewed beam–column connections, and (2) straight cleated beam–beam connections. Nonlinear static and dynamic analyses were performed and then the time history analysis was performed under the simultaneous effect of the two horizontal components of three earthquake records and two column removal scenarios. The results showed that the 60-degree skewed connection had a weaker performance than the straight connection, and, according to the plastic hinge distribution, it was observed that the mentioned connection did not provide the life safety performance level.
