The aim of this study is to reveal the effect of horizontal restraints on the progressive collapse behaviour of precast concrete (PC) framed substructures. To this end, two one-thirds-scale 2-storey 2-span beam-column sub-frames with varying horizontal restraint conditions have been experimentally investigated. A nonlinear finite element (FE) model based on ABAQUS package was established and validated against failure modes and load-carrying capacity recorded in the test. Parametric studies were conducted using the FE simulation approach to investigate the effect of key design variables on the performance of the PC sub-frames. It was found that the failure of the PC beam-column assemblies was dominated by pull-out of anchorage bars on side joints and the load-carrying capacity of the PC sub-frames were considerably affected by horizontal restraints.
