description abstractPrecast prestressed hollow core slabs (PPHCSs) are widely used in the construction of multistory cross-wall structures, but the floors are vulnerable to progressive collapse induced by unexpected loadings due to weak links between PPHCSs. Despite this fact, limited studies have been carried out on the progressive collapse resistance of PPHCSs. In this study, quasi-static tests were conducted to evaluate the progressive collapse resistance of PPHCSs. The test parameters were the types of connectors [i.e., single rebar connector (S1), double rebar connector (S2), partially debonded rebar connector (S3), kinked rebar connector (S4), and partial hinge rebar connector (S5)]. The progressive collapse resistance including the load-carrying capacity, deformation capacity, failure modes, and main load-resisting mechanism was evaluated. The energy dissipation capacity of all specimens was estimated based on the energy balance principle, and the energy dissipation capacity of S5 was 91%, 303%, 190%, and 85% greater than that of S1–S4, respectively. Further, the pseudo-static response of each specimen was calculated using a simplified dynamic assessment method. The test results revealed that all specimens generated effective compressive arch action and catenary action, and the ultimate strength (72.56 kN) of S5 using partial hinge was 64%, 334%, 110%, and 45% greater than that of S1–S4, respectively.
