Corfar, D. A. & Tsavdaridis, K. ORCID: 0000-0001-8349-3979 (2023). Proof-of-Concept Finite Element Analysis of a Novel Hybrid Inter-Module Connection. Paper presented at the The 17th Computational Civil Engineering (CCE 2023) - Embedding Digital and Green for Resilient Constructions, 24-25 May 2023, Iasi, Romania.


Inter-module connections (IMCs) play a crucial role in the structural behaviour of steel Modular Building Systems (MBSs) by ensuring the vertical and horizontal load-transfer paths between modules, yet existing designs display limited disassembly opportunities and lack damage control features. This study introduces a novel, hybrid demountable IMC comprising bespoke corner fittings, a resilient high-damping rubber core and a shape-memory alloy (SMA) bolt. Proof-of-concept connection tests have been carried out using validated, continuum finite element analysis (FEA) to determine the mechanical behaviour of the proposed IMC with respect to the main deformation modes expected to occur in the joints of tall steel MBSs under the combined effect of vertical and horizontal loading. Main findings show that both the HDR core and the SMA bolt contribute effectively to the overall hybrid response of the IMC under tension and combined compression and shear loading, preventing the formation of significant plastic damage in the MBS’s corner fittings to facilitate reusability of modules.
