“…Of note, both Wolfe [5] and Patton-Mallory et al [1] found that the overall capacity of the shear walls could be predicted accurately by summing the capacity of the component parts of the system. Liew et al [2] found that walls with plasterboard fixed on one side of the shear wall using screws, but no adhesive, achieved ultimate capacities of 2.0 -3.5 kN/m. This result is far better than the nominal design capacities in AS1684 [4].…”

“…Adjusted displacement then is: (1) where is the multiplier obtained from curve-fitting using the nonlinear least squares optimisation described above. Racking displacement can also be corrected to remove the sliding and overturning components to obtain the shear component of the displacement: (2) where, and are the height and length of the test panel.…”

“…It is common practice to use only structural elements in a test panel, such as timber framing, sheathing, connectors, tiedowns and anchors. Plasterboard, also known as gypsum board or drywall, is rarely attached to laboratory test panels even though it is ubiquitous in residential construction and known to provide some strength and stiffness (e.g., [1,2]). Here, we report on our experimental test plan to quantify the influence of plasterboard on the structural performance of timber-framed shear walls.…”

Timber-framed shear walls are commonly used in residential buildings to provide lateral strength and stiffness against wind and earthquake loads. Wood-based panel products, such as plywood and oriented strand board, are typically fixed to timber framing with nails or screws to provide the necessary racking resistance of a shear wall. Plasterboard is a panel product used on walls to achieve a smooth finished surface. Plasterboard provides some strength and stiffness to the wall even though its primary function is architectural; however, most shear wall tests ignore the influence of plasterboard. The aim of this study is to quantify the influence of plasterboard on the structural performance of timber-framed shear walls. To achieve this aim, six (6) timber-framed shear walls (groups P1 and P2) were fabricated with 7mm F8 plywood sheathing on one side and 10mm plasterboard on the other side and tested under a monotonic loading protocol. Results were then compared with previous test results of three (3) similar timber-framed shear walls (group M1) without plasterboard. Results show that plasterboard improved the ultimate racking strength of these shear walls by up to 53%, a statistically significant result. Shear wall stiffness and failure modes were not affected by adding plasterboard.

As the first part of non-structural component test series, interior drywall partitions are selected for an experimental program. This test series will cover non-structural components that are significant in the economic losses in buildings subjected to seismic loading, namely interior drywall partitions, exterior cladding and window glasses, and ceilings. Four full-scale drywall partitions with light-gage steel stud framing were tested to observe damage in cyclic loading conditions. Effects of a door and an intersecting wall on the behaviour of drywall partition are studied. Damage was concentrated to perimeter regions where gypsum boards made contacts with ceiling, floor, or columns. Dynamic loading did not amplify the damage on a drywall partition over the damage observed from the quasi-static test. Damage-repair cost relationships show that the repair cost reaches almost the initial cost under 2% radian interstorey drift. components is one of the most critical elements of the PBEE methodology. Unlike structural components, most of the non-structural components, including architectural, mechanical, electrical, and plumbing components, are vulnerable to a relatively low level of earthquake. According to reconnaissance reports for recent earthquakes, namely 1989 Loma Prieta, 1994 Northridge, and 2001 Nisqually earthquakes [1-3], economic loss due to non-structural components generally exceeds that due to structural components. Taghavi and Miranda [4] studied the distribution of the original construction cost for three types of buildings, namely offices, hotels, and hospitals, in terms of structural components, non-structural components, and building contents. The cost of non-structural components is the highest for all three types of buildings where its portion ranges from 48 to 70% of the total cost. According to Hirakawa and Kanda [5], the cost of non-structural components is 40% for 210 reinforced concrete (RC) buildings damaged from the 1995 Hyogo-ken Nanbu earthquake, while that for structural components is also 40%. Consequently, it is widely agreed that the mitigation of non-structural damage will dramatically improve the protection of structures from economic losses.Among various non-structural components, the interior architectural component is one of the most significant contributing components. Taghavi and Miranda [4] reported that interior constructions and mechanical systems are the major source of cost (20-30% of the total non-structural component cost of the original construction, for different types of building), while electrical systems and exterior closure cost almost 10% of the total based on their investigation for various building types, namely a mid-rise apartment, a hospital and office building, and a high-rise hotel. The other non-structural components such as elevators, escalators, and roofing do not contribute more than 5% to the total non-structural component cost.Despite the significant amount of research already conducted within the framework of the PBEE methodology, there is limite...
