“…Compliance of these new systems is normally confirmed by laboratory based testing of the individual subassemblies or components. However, based on testing of full scale houses it has been established that the overall lateral behaviour inherently incorporates contributions from the main structural elements and from the so called non-structural components, particularly plasterboard lining (Reardon [1] and Gad et al [2]). This paper reports the findings of a detailed investigation into the actual loading mechanism of plasterboard clad frames and the influence of the actual load paths on the design assumptions for such structures.…”

While the design and technology of conventional low rise light framed residential structures are relatively simple, their response to lateral loading is quite complex. This is due to the high degree of redundancy, the irregular geometry and interaction between the structural and non-structural components. In addition, the designated lateral bracing elements within one structure may exhibit significantly different behaviour due to the different bracing actions and different materials. This paper focuses on the bracing capacity of plasterboard clad walls which could be considered either structural or non-structural. While such walls may be installed purely as partition walls, they may provide lateral strength and stiffness due to the complex load paths. The paper presents in detail the possible load transfer mechanisms to a variety of typical walls. It also highlights the difficulty with performing racking tests on isolated walls due to the complex boundary conditions surrounding walls in real structures. In addition, the paper reports racking test results that demonstrate the effects of different boundary conditions on the load carrying capacity and the failure modes.

There has been a significant worldwide increase in the use of cold-formed steel (CFS) in low-rise residential structures as an alternative to timber. Improving the understanding of the behaviour of cold-formed steel framed domestic construction is important considering the greatly increased worldwide demand for such structures. CFS structures are used in many parts of the world including areas of moderate to high seismic activity such as Japan, the United States, and New Zealand and areas with cyclonic winds such as some parts of Australia.Australia is at the forefront of this technology, and its systems are most advanced worldwide, although due to the low seismicity in this region, little attention has been paid into studying the behaviour of CFS structures under earthquakes. The current study is one of the very few that investigates the lateral load capacity of CFS structures in addition to other properties of these systems. Lateral load resisting capacity of this system is usually its Achilles heel. The common bracing methods are not capable of economically resisting the high demands imposed on the system in high seismic regions or high wind areas.This study aims at evaluating the extra capacities that can be obtained by some common or not-so-common additional material such as screw fixed gypsum board in isolation or in combination with fillers such as foam-concrete. The CFS structure made in combination with fillers is called HYBRID in the current study. The filler material restrains the buckling of studs to some extent and participates in carrying the loads. As part of this study, an innovative bracing system is developed that works well under earthquake loads. The brace allows dissipation of energy to occur through yielding of strap braces over a long length without any failure at the connections or at the tensioning units.
