Steel modular construction presents a modern and efficient method of building, serving as an alternative to traditional construction practices. The rise in popularity of steel modular buildings addresses the growing demand for infrastructure in large cities. The key component of a steel modular building is the connection between the beams and columns. The VectorBloc connector is an innovative cast-steel connector which involves hollow structural steel (HSS) members to hold the building together under various loading conditions. The previous research on VectorBloc corner connection focused on its behavior under design axial tension and compression loads for a mid-rise living facility in Ontario. The structural behavior of a new bundled column VectorBloc corner connection is investigated in this study for potential application in construction of the high-rise buildings. This research presents the performance of the connection under axial compression loads through the results of full-scale experimental test and finite element analyses. This study shows that bundled column VectorBloc connection is able to carry the design load without compromising the strength of the connection. A parametric study is also conducted to propose recommendation to improve the connection capacity.
