Seismic performance of high-capacity light wood frame shear walls with three rows of nails

Experimental and Numerical Analysis of High-Capacity Shear Walls With Multiple Rows of Nails

“…The objective of this study is to develop a detailed 3D shear wall model to predict the structural performance of high-capacity shear walls and simulate the failure modes including those that are not common in regular shear walls. The numerical models of high-capacity shear walls with three rows of nails were verified with the test results obtained in previous research by the authors [4]. Detailed wall components and boundary conditions were included in the model to regenerate the lateral behavior and failure modes of high-capacity shear walls tested in the lab.…”

“…To respond to this demand, a high-capacity shear wall system with multiple rows of nails along sheathing edges has been jointly developed by FPInnovations and University of Victoria. There were 30 high-capacity shear walls with two and three rows of nails along sheathing edges tested over a three-year period [3,4]. Results showed that the lateral resistance of shear wall with multiple rows of nails is almost proportional to the number of rows.…”

“…A better understanding on the stressstain development of sheathing panels, framing members and connections is needed to develop design details to prevent these undesirable brittle failures and increase the ductility and design resistance of wood shear walls with multiple rows of nails. Numerical models of light wood frame shear walls have been developed with different methods in the past [4].…”

Muros de entramado ligero de madera: Una revisión del estado del arte

“…Qiang et al [25], presentan una variación constructiva al conectar los paneles de revestimiento al marco con tres filas de clavos en lugar de una sola alrededor de los bordes. Tras ensayos cíclicos en 10 especímenes, se encontró una resistencia lateral hasta tres veces más que la de muros estándar.…”

“…En los estudios expuestos en el apartado de variaciones a la geometría y detalles constructivos de los muros, se evidencia que las pruebas se hacen con carga cuasiestática monotónica o cíclica [3,4,5,19,21,24,25]. No se ha encontrado, al menos dentro de las limitaciones de búsqueda en esta investigación, que los prototipos propuestos por los distintos autores hayan sido sometidos posteriormente a ensayos donde se emplee una mesa vibratoria para determinar su comportamiento bajo excitación sísmica.…”
