Abstract

Three cyclic tests with bi-axial loading were carried out on meso-scale inter-module joint assemblies using a novel hybrid inter-module connection with high-strength steel bolts and rubber bearings in order to determine the mechanical behaviour of the proposed connection at joint level. The tests also included different intra-module connection details and bolt sizes. The results showed that all three hybrid IMJs displayed nonlinear hysteretic responses, while the presence of stiffeners at the intramodule connection and the larger bolt size had a favourable effect on the failure mode, lateral load capacity and stiffness degradation of the joints. According to Eurocode 3, the hybrid joints were classified as semi-rigid, partial strength in terms of stiffness and strength respectively. Furthermore, the strain analysis results demonstrated the feasibility of the proposed connection with respect to the limitation of damage in the structural elements of the volumetric under cyclic lateral load, improving the reclaim and reuse potential of the module.
