“…The earliest experimental studies of timber-framed partitions [32][33][34][35][36][37][38] focused on understanding their seismic behaviour by investigating the contribution of different sheathings (gypsum plasterboard, oriented strand board, plywood) and their orientation, wall openings, interior and external finishes, type and spacing of screws and boundary restraints (such as return walls, ceiling cornices, and skirting) on the lateral load resistance and failure mode of the walls. The tests conducted by Arnold et al [39,40] explored the response of timber-framed walls with boundary conditions typical of single-story structures and the first-story walls of two-story structures, in addition to determining the efficacy of various stucco and plasterboard repair methods.…”

“…The shear strength calculated using equation 1 is conservative for rigid timber-framed walls as it is solely based on the shear strength of screws. It has been observed that the performance of walls generally depends on the type, size, and frequency of the screws (and/or adhesives), type and thickness of the plasterboard and the material properties, hold-down details, and the type of joint finish [32][33][34][35][36][37][38][39][40][44][45][46]. It is found that the plasterboard-toframe screws can maintain their load-carrying capacity during the bearing failure of the plasterboard, and as a result, the actual shear strength is higher than that given by equation 1 by a factor of 1.3 [52].…”

This paper identifies the inherent strengths/weaknesses of rigid timber-framed partitions and quantifies the onset drifts for different damage thresholds under bi-directional seismic actions. It reports construction and quasi-static lateral cyclic testing of a multi-winged timber-framed partition wall specimen with details typical of New Zealand construction practice. Furthermore, the cyclic performance of the tested rigid timber-framed partition wall is also compared with that of similar partition walls incorporating ‘partly-sliding’ connectiondetails, and ‘seismic gaps’, previously tested under the same test setup. Based on the experimentally recorded cyclic performance measures, theoretical equations proposed/derived in the literature to predict the ultimate strength, initial stiffness, and drift capacity of different damage states are scrutinized, and some equations are updated in order to alleviate identified possible shortcomings. These theoretical estimates are then validated with the experimental results. It is found that the equations can reasonably predict the initial stiffness and ultimate shear strength of the partitions, as well as the onset-driftscorresponding to the screw damage and diagonal buckling failure mode of the plasterboard. The predicted bi-linear curve is also found to approximate the backbone curve of the tested partition wall sensibly.

“…Small-scale wall racking tests have been utilized to evaluate sheathing materials and predict full-scale wall racking behaviors (Tuomi and Gromala 1977, Price and Gromala 1980, McCutcheon 1985, Patton-Mallory et al 1985. The work of McCutcheon (1985) and Patton-Mallory et al (1985) suggest that it is possible to predict full-scale wall racking behavior by small-scale racking tests. McCutcheon's (1985) work also found that a small-scale racking test yielded a more reliable prediction than the nail resistance test (Patton-Mallory et al 1985).…”

Racking strength of paperboard based sheathing materials

Small-scale racking testers were developed for use as a means to evaluate paperboard-based sheathing materials used in framed wall-construction. For the purpose of evaluating the performance of different sheathing materials, the tester provides an economic alternative to standard full-scale racking tests. In addition, results from testing provide practical insight into the racking response of framed and sheathed walls. The load-deformation responses of three commercial sheathing boards were measured, and initial racking stiffness and racking strength were proposed as parameters for characterizing the board. The racking test results showed that the initial paperboard racking stiffness correlated to elastic modulus and caliper, but the response was insensitive to paperboard orientation or test dimensions. Observations and results showed that both panel buckling and paperboard cutting at the staples affected the racking response, but the dominating factor influencing the racking response appears to be load transfer through the staples.

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.
