Behaviour of Beam–Column Connection of Modular Steel Buildings
Prefabricated modular structures are becoming more popular in the construction industry, where structural components are prepared off-site leading to accelerating the construction phase. The prefabrication process can eliminate any unpredicted variables, ensure high-quality control, and reduce environmental waste. Modular steel structures have been widely adopted over the last few decades to create structures consisting of repetitive units in houses, tall buildings, and bridges, in addition to being useful for temporary structures. The lateral load (e.g., wind or earthquake) performance of modular structures relies on the interconnections between modules to ensure robustness and structural integrity, instead of the need for an additional structural system. Although volumetric modular structures have been widely used where the entire three-dimensional module is constructed off-site, this type of module is not ideal for transportation. Moreover, the transportation and lifting process of these units can lead to the risk of damaging structural and non-structural members. Alternatively, panels (i.e., two-dimensional modules) can be manufactured off-site and then assembled using bolted connections on-site to avoid limitations of transportation. The current study aims to assess the mechanical performance of beam–column connection for steel modular structures under monotonic loading. Different pretensioning forces have been examined to investigate their impact on connection performance.
