Implication

Numerical assessment reveals that precast slabs enhance progressive collapse resistance in spatial frames, indicating improved safety design strategies.

Key Points

The study shows that precast slabs significantly improve the progressive collapse resistance of spatial frames.
Pushdown analyses reveal the collapse mechanism transitions from beam action to catenary action when columns fail.
Finite element modeling was validated against test data to accurately assess the collapse performance of frames.
Dynamic assessments indicate that these frames maintain high ductility and residual strength after column removal.
