“…Due to a lack of guidelines and code of practice, the design of modular structures has been subject to investigation by many researchers [2][3][4][5][6][7][8][9][10][11][12][13][14][15][16]. In recent years, a number of intermodular connections has been proposed, and their seismic performance under monotonic and cyclic loading has been evaluated experimentally and analytically [17][18][19][20][21][22][23][24]. Lawson proposed a single bolt joint to connect an upper and lower square hollow section (SHS) and angle section column of modules [25], as shown in Figure 1a.…”

The intermodular connection between modules plays a vital role in the overall performance of modular structures. The separation between a column and connection is possible due to the absence of links (welding or bolting) since limited space is available between modules. This study proposed a self-locking joint to be used in a modular steel structure, connecting columns with a connection without need of extra space between modules. The behavior of the proposed connection subjected to monotonic load was evaluated using a finite element approach using ABAQUS software. The influencing factors contributed to the behavior of the self-locking connection and columns observed using a parametric study. The parametric study was conducted by varying beam thickness, bolt pretension force and friction coefficient µ. Results indicate that the proposed connection can be classified as a semirigid connection according to Eurocode 3 and special moment frame (SMF) as recommended by AISC.

“…investigated the bearing capacity of a full-scale modular unit under vertical and lateral loadings by using means of tests and FE analysis [28]. The studies previously recorded were found to be confined to the performance of corner joints, simplified frames or modular units without any proper detailed behaviour of connections, use of weaker sections and access holes, while, very least attention was paid to the behaviour of complex form of joints, i.e., middle joint, simplification of the joint to overcome computational efforts, combined effect of forces on the behaviour of modular units with the developed joint and the overall dynamic response of MSB against real earthquake accelerograms [8,24,25,27,29,30]. The main aim of the current study was to develop a newtype of bolted joint, analyse its bending performance, simplify and apply it in the full-scale modular units, and evaluate the overall seismic performance of the developed simplified multi-storey MSB.…”

Prefabricated modular steel (PFMS) construction is an industrial technique of construction that enhances productivity, site safety, and construction quality. The assembling of prefabricated buildings needs an accurate connecting system to ensure structural integrity and effective transfer of loads and moments. Therefore, in the current study, a new-type bolted joints having a long tenon-gusset plate for horizontally, and long beam bolts for vertically connecting modular units have been developed. Nonlinear static analysis was carried out by the finite element (FE) analysis software ABAQUS. The bending performance of the joints with varying parameters and modular units with different forces scenario, was studied. To analyse the seismic performance of modular steel building (MSB), a simplification of the detailed joint with the connector was performed. Then the seismic response of full-scale four-storey simplified MSB was studied by dynamic analysis. The results revealed that joints possessed stable load-carrying capacity with adequate ductility and seismic performance. The simultaneous application of axial, lateral tension, and compression forces affected ultimate capacity, initial stiffness, and ductility of single modules more than the double modules. Moreover, the simplified model accurately mimicked the bending behaviour of joints with a fluctuation of < 4% in capacities. Inter-storey drift ratios (IDR) of both the shorter and longer directions of MSB were found lower than the code limits of 2.5%. Hence, the static analysis on joints and modular units, and dynamic analysis on MSB authenticated the effectiveness of developed joints to resist and distribute the lateral loads. Finally, the accuracy of FE analysis was verified by analysing twelve bending tests on joints listed in the references.
