Connection and system performances of steel prefabricated and modular structures

Prefabrication and modular construction are methodologies to maximize manufacturing of structural components or even complete systems in factory for assembly on site in order to improve productivity over conventional on-site construction. In this PhD study, the mechanical properties of beam-column connections and column-column connections designed exclusively for steel prefabricated and modular buildings are investigated. The resulting overall system performances of building modules or prefabricated structures subjected to critical loading scenarios such as lateral accelerations during road transportation for individual building modules or seismic ground accelerations during earthquake for tall prefabricated buildings are investigated.
