Abstract

This paper involves a fundamental study of a numerical method for progressive collapse resistance design of floor-to-floor joint in the precast cross wall structures. It presents a 3D numerical study of floor-to-floor system with longitudinal and transverse ties. The model is also used to derive, the post-bond-behaviour and the mechanism of forming catenary action in relation to the bond behaviour in precast cross wall structures. The results obtained inform indicate the adequacy and applicability of the code specifications in British Standard, Euro Codes and DoD 2013. Discrepancies in the tie force between the numerical results and codified specifications have suggested that an inappropriate use of current TF method, hence improved model based on the numerical results has been proposed to address this concern. To the authors’ best knowledge, this is the first numerical study to investigate the behaviour of floor-to-floor joints following the removal of a wall support in typical precast cross wall structures when considering bar fracture and pull-out failure mode.
