Deflections Estimation of Light Wood-framed Shear Walls Without Hold-Downs

1 Cyclic Tests of Full - Scale Light - Framed Wood Construction

Nine full-scale light-framed wood construction (LFWC) specimens were tested cyclically to study the effect of the upper storey and the vertical load on the performance of wall framed shear wall (WFSW) in the first storey. Results showed that the effects of the upper storey with the vertical load on the performance of WFSW were to: (1) increase the elastic stiffness, (2) reduce the ultimate defl...

Seismic capacity rating and reliability assessment of wood shear walls

A modified version of the BRANZ procedure for lateral capacity rating of bracing walls is used to determine the sustainable lateral mass of a 910-mm wide ‘2x4’ wood shear wall. The key modifications involve: (1) the use of a multicriteria system identification method to determine a structural model that simultaneously fits test data from both cyclic testing and pseudo-dynamic testing; and (2) p...

Effect of Overturning Restraint on the Performance of Fully Sheathed and Perforated Timber Framed Shear Walls

Slip Modeling in Timber-Framed Walls with Wood-Based or Fibre-Plaster Sheathing Boards

The paper provides mathematical modelling for prefabricated timber-framed walls composed of a timber frame and two different types of sheathing boards. Since by wood-based boards (WBB) the tensile strength is similar to the compressive one, there are practically no cracks appearing in the boards. On the other hand, in case of fibre-plaster sheathing boards (FPB) the tensile strength is approxim...

Cyclic Testing of Light-Gauge Steel Plate Shear Walls

This paper describes the prototype design, specimen design, experimental set-up, and experimental results of tests on three light-gauge steel plate shear wall (SPSW) concepts. Prototype light-gauge steel plate shear walls are designed as seismic retrofits for a hospital structure in an area of high seismicity and emphasis is placed on minimizing their impact on the existing framing. Three singl...
