Offsite volumetric modular construction is getting considerable attention within the construction industry, especially in relation to the housing market. The study reported in this paper focuses on the design and testing of a lifting system for an offsite modular prototype made with light gauge steel members. The motivation of the research starts from the need to improve the design for lifting light gauge steel frames in modular construction. As time is critical in modular construction, the lifting method should be reliable and provide easy setup in the factory as well as onsite.
A desk study was carried out to outline the most practical solutions, then the module lifting locations were assessed to minimize deflection of the frame during lifting. The stability of the units and the local failure of the member were both considered. The lifting bracket was then designed with guidance from the European Standard EN 1993-1-2:2005. However, as the design of the lifting bracket is unique a set of experimental tests were carried out in the Heavy Structures Lab of Queen’s University Belfast. The specimens, made connecting steel studs to connection brackets, were tested in tension in a Zwick Roell universal machine to replicate the modular house lifting conditions. The specimens were tested up to failure.
The testing showed the flaws of some of the designs and allowed to evaluate the tensile capacity of the lifting system. The modular house modules were manufactured in December 2017. The modular units were successfully lifted and connected to each other to form a three-bedrooms offsite volumetric house.
