Abstract: With the recent increased use of precast concrete (PC) structures, their progressive collapse resistance under hazardous conditions, such as explosion and fire, has become a great concern for the structural engineering community. In this study, static push-down tests were performed on eight PC beam-column substructures, in a column removal scenario due to fire, to investigate their progressive collapse resistance. The test specimens were classified into four groups, and static loading was applied to them under and after fire in a specially designed hybrid heating furnace. The test parameters were the wet-connection details in PC beam-column joints and the timing of high temperature. Structural performance and failure modes were evaluated, including thermal responses, load-displacement relationships, temperature–axial force relationships, and beam moment–axial force relationships. The test results showed that in the joint specimens using a lap splice connection and/or at high temperature, insufficient compressive arch action (CAA) and catenary action (CTA) developed.
