Abstract

This paper involves a fundamental study of a numerical method for progressive
collapse resistance design of floor-to-floor joints in precast cross-wall structures. It presents a 3D
numerical study of a floor-to-floor system with longitudinal and transverse ties. The model is also used to derive the post-bond behavior and the mechanism of forming catenary action concerning the bond behavior in precast cross-wall structures. The obtained results indicated 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 an inappropriate use of the current TF method, hence, an 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 behavior of floor-to-floor joints following the removal of wall support in typical precast cross-wall structures when considering bar fracture and pull-out failure mode.
