Modular construction is becoming widely present on the construction market not only in form of temporary
facilities but also as permanent single-family homes, multi-residential buildings, tourist facilities,
office buildings and public buildings such as schools and daycares. This is mostly due to significant
developments of modular building technologies in recent years, which enable larger and taller modular
buildings, meeting all building regulations and standards, as well as enhanced living quality in terms
of energy performance, acoustics, room sizes and indoor quality. Due to easy transportation and fast
assembly time, it can assure rapid response to natural disasters (earthquakes, floods, landslides, etc.),
refugee crisis or health crisis (pandemics) in terms of providing temporary or permanent accommodation
to the affected population, or even relocation of these facilities to a different location according to the
needs.
On the other hand, modular structural systems usually consist of more flexible and less resistant slender
structural elements which are separated from each other in individual modules, therefore the global
continuity of the entire building’s structural system may be compromised, especially in the lateral
direction. In this study, the development of a seismic-resistant timber-steel hybrid shear wall system
for multi-storey modular buildings in moderate to high wind and seismic areas is presented. The main
aims were to increase the vertical and lateral strength and stiffness capacity of the current modular unit
solutions with environmentally friendly timber structural elements. The main lateral load resisting system
consists of a steel frame with infilled light timber frame shear walls. After a preliminary analytical and
numerical analysis, full-scale monotonic and reverse cyclic tests according to EN 12512 standard on two
sets of hybrid shear wall systems was performed to determine their seismic behaviour properties. The
proposed solution shows potential for application in multi-storey modular buildings.
Keywords: hybrid timber-steel shear wall, hybrid structural system, multi-storey modular construction,
