This paper presents the results of seventeen in-plane monotonic and cyclic shear tests in wood frame shear walls of different lengths (, and mm) and mm height. The walls have five 2 × 6″ end studs, strong hold-down anchorages and standard mm structural OSB panels ( × mm) on both faces of the wall and with Cited by: 3.
They proposed methods for a more accurate prediction of cyclic response of the shear walls in order to develop a solution to properly design wood frame shear walls, providing the walls with adequate strength and stiffness.

Findings from the study indicate that nonstructural finish materials have a substantial influence on the performance of woodframe shearwalls, causing increases in strength and stiffness, and reductions in deformation capacity.
The influence of reinforced nailing on the static and dynamic performance of full-size wood frame shear walls with large openings, sheathed with OSB panels, was evaluated experimentally. Combinations of parameters were studied, such as the number of hold-downs, the panel shapes, the nail distribution, and the bracing systems.
A pilot study was conducted at Penn State University to determine whether the type of drywall joint compound would influence the shear strength of wood-frame stud walls sheathed with Gypsum Wall Board (GWB or drywall).
In this study, five mm by mm specimens were tested under in-plane cyclic racking loading following the CUREE loading protocol for light-frame wall systems. Figure 1: Factors Affecting Lateral Behavior of Shear Walls.
Lateral force resistance to wind and seismic loads in wood frame structures is provided by shear walls in the majority of homes (Shirazi and Pang ). In this configuration, shear walls resist forces by allowing the sheathing panel to rotate, essentially racking.
Timber platform-frame shear walls are characterized by high ductility and diffuse energy dissipation but limited in-plane shear resistance. A novel lightweight constructive system composed of steel columns braced with oriented strand board (OSB) panels was conceived and tested.
Preliminary laboratory tests were performed to study the OSB-to-column connections with self-drilling screws. Then. transfer from diaphragms to shear walls or frames. Part C discusses wood-framed, shear-wall construction including stiffness issues and hold-downs. Earthquake Performance of Wood-Frame Buildings Buildings are at rest when an earthquake arrives, and then are suddenly accelerated laterally by horizontal earthquake ground motion (Figure 1).
Dowels and bolts are well established types of fasteners for timber connections. They are fast and easy to assemble which made them become a common solution for joining heavy timber elements. This study investigates the feasibility of bolted connections as a possible anchoring solution for heavy shear walls under seismic loads.
Fully reversed cyclic tests were performed on glued laminated. two shear walls for each configuration (Gatto and Uang ). Although this may be acceptable in many instances, it leaves open the question of how much variability should be expected based on materials and construction.
Folz and Filiatrault () emphasized the need to quantify the varia-bility in the response of shear walls under load.

Reitherman and K. Cobeen: W shear walls with different joint finishes. Prior to widespread use of cyclic loading, many wall tests were carried out using static monotonic loading. These monotonic testing procedures have long been standardized as ASTM E72  and ASTM E .

Structural Engineers World Congress (SEWC?98), San. This paper describes the full-scale test program of a code-conforming Post and Beam shearwall system conducted in a curtain wall test facility.
The two-story test specimen is taken from a slice of index full-scale test structure to represent the first-mode dominant response properties. The design of the full-scale index building was carried out following the code requirements of wood buildings. step (cyclic analysis) each single woodframe wall is numerically analysed on the basis of the known inelastic behaviour of fasteners.
The result of analysis is a hysteretic response of the wall. This response is a source for the derivation of mechanical characteristics of inelastic spring that.
The need for comparable loading histories for seismic acceptance testing is becoming more prevalent as (a) performance-based design, which requires quantification of performance, is becoming a more widely accepted alternative to routine code design, (b) more and more innovative performance enhancement systems (e.g., buckling restrained braces) hit the engineering market, and (c) globalization.

Parameters, such as peak [ ]. basis that, “Wood-frame buildings are known to perform well in earthquakes.” 3 These endorsements of the ability of wood-frame construction to perform well in the face of earth-quakes are based on several researched and docu-mented wood building system characteristics.
“Wood-frame buildings are known to perform well in earthquakes.” 3. Given that the cyclic response of wood shear walls is non-linear under essentially all load levels, the identification of a yield point is problematic.
It is commonly specified in order to establish the ductility of the wall. Currently, there is no consensus on the specification of the onset of yielding in wood shear walls. The design procedures for RC shear walls, however, do not take into account these key features of hysteretic response.
There is no design code that mentions any criterion requested to reserve the ultimate resisting capacity and the corresponding ductility for a RC shear wall subject to cyclic loadings.
Analytical models of wood-frame shear walls and diaphragms for use in monotonic, quasi-static (cyclic), and dynamic analyses are developed in this thesis.
A new analytical model is developed to accurately represent connections between sheathing panels and wood framing members (sheathing-to-framing connections) in structural analysis computer programs. Shear Walls & Diaphragms When designing a building for lateral loads such as those generated by wind or earthquakes, a design engineer may have several alternatives.
Lateral loads may be transferred to the foundation via braced frames or rigid frames, diagonal rods or "X" bracing, including let-in bracing in the ease of wood frame construction. The proposed light-frame structure comprises steel columns for vertical loads and an innovative bracing system to efficiently resist seismic actions.
This seismic force resisting system consists of a light timber frame braced with an Oriented Strand Board (OSB) sheet and an external technoprene plaster-infilled slab.
Steel brackets are used as foundation and floor connections. Seismic Response of Wood-Frame Construction Part C: The Role of Wood-Framed Shear Walls Briefing Paper 3 Introduction This Briefing Paper 3, Seismic Response of Wood-Frame Construction, consists of three parts that discuss how earthquakes affect wood-framed construction, including specifics regarding their earth-quake-resisting elements, and.
Tests have been conducted on wood frame shear walls to characterize the degradation of stiffness and energy dissipation that occurs under cyclic loading. A total of eight walls were tested, four sheathed in plywood and four sheathed in oriented-strand board. Progress 11/15/02 to 11/14/06 Outputs The objectives of this research were: (1) to understand the behavior of wood-frame shear walls under various actual dynamic loading records, and (2) to compare the behavior of shear walls under the standard static test (ASTM E) and cyclic test protocol (CUREE) to the behavior of the shear walls subjected to various actual dynamic loading records.
