Abstract

Connections or joints are the fundamental components that bring together individual three-dimensional volumetric modules to form a complete modular building. Due to the discontinuous nature of corner-supported modular buildings, high concentrations of stress develop within the connections. The structural capacity of connections should be well defined to effectively create a continuous structural building system. However, the design of reliable intermodular connection remains a significant challenge. This research reviews and remodels two proposed connection models and combines the two selected intermodular connections to create an innovative individual intermodular connection model. The modelling has been completed through numerical simulation in the FEA software ABAQUS v.2019 to reveal and compare the behaviour of the three proposed intermodular connection models. The simulation has been conducted across a range of loading scenarios to compare and determine the behaviour of the intermodular connections. The numerical analyses revealed an improved response for the novel intermodular connection model under all applied loading scenarios. This study has shown that the combination of interlocking plates, shear keys and a post tensioned rod can significantly improve the IMCs performance under a range of loading applications.
