Abstract
Today, modular construction has emerged as a cost-effective and efficient alternative to conventional onsite construction approaches. It enhances quality control and minimizes construction waste and associated expenses. Steel modular construction, in particular, is gaining popularity as a viable solution to address the rising infrastructure demands in urban areas. The VectorBloc modular construction method is noteworthy for its distinctive utilization of steel modules constructed from hollow structural steel (HSS) elements, connected through the innovative VectorBloc connection system. The findings of this study demonstrate that the registration-pin connection can securely carry the volumetric module during installation. Moreover, an empirical equation is proposed in this study to predict the failure behaviour of registration-pin connections subjected to angular loads, specifically related to the stripping of threads. The impact of different connection parameters on the structural behaviour of column-to-column connections is also discussed in this study. Through full-scale tests and finite element analyses of these connections, the tensile capacity of these connections is calculated, and design recommendations are proposed. The other aspect of this research is the serviceability of the floor in the Vectorbloc modular construction system concerning its vibration performance under human-induced loads. The findings of the numerical study, experimental investigations, and finite element analyses reveal that the VectorBloc modular construction system can provide a comfortable floor performance for various occupancies, even when subjected to different loads such as walking, aerobics, and group dancing.
