“…In the corner of the sheathing panels, the nail head embedding (Figure 5b) and the relative displacement between panels (Figure 5c) were observed. As to the common failure modes, e.g., nail pull-through, nail withdrawal and the pull-out of the vertical studs, as reported in [12,[32][33][34][35], they were not observed in this test. The yielding in the PT frame was also not observed.…”

Due to timber material’s environmental benefits and satisfactory structural properties, the studies on providing solutions to the application of timber to mid-rise or even high-rise buildings have been recently increasing. Among them, the steel–timber hybrid shear wall (STHSW) is one of the promising lateral resisting systems. However, the application of the system is limited because of its unsatisfactory earthquake resilience. In this paper, a new system, self-centering (SC)-STHSW, is proposed by introducing post-tensioned (PT) technology into the STHSW system. The cyclic loading test of one full-scale SC-STHSW specimen was conducted. The new system was proved to have both satisfactory self-centering capacity and the sufficient energy dissipation. Within the OpenSees platform, a numerical model was developed and validated by the experiment result. The model was further used in the parametric analysis. The system’s self-centering capacity, energy dissipation performance and the ultimate strength were evaluated under multiple parameters. The parameters included the initial PT stress ratio, the relative value of the damper’s activation force, the wood shear wall’s resistance, the beam section height and the wood shear wall’s strength. The lateral wall-to-frame stiffness ratio was also considered. Each parameter’s effects on three different performances of the system were analyzed. Based on the analysis results, a design parameter, a self-centering ratio, was proposed. The ratio was suggested to be larger than 0.5 to ensure a favorable self-centering performance in the system. This study provides support to the application of the innovative steel–timber hybrid structural system in practical engineering.

“…The shear walls underwent only limited deformation (at the top of the walls) and adequately braced the structure. For instance, the maximum displacement was 45 mm for GUA 390%, whereas a modern timber-framed wall [OSB12 panels with 1.5 tons at the top of the wall (Humbert et al 2014 andBoudaud et al 2014)] reaches 44 mm for GUA 320% (and in similar experimental configurations: ground motion, shake table, etc.). The global hysteretic response has been analyzed through the base shear versus the top displacement of both the transverse wall and shear wall.…”

The seismic performance of timber-framed structures filled with stones and earth mortar has been analyzed by introducing the structural subscales (cell, wall, house) at which monotonic and cyclic loadings were considered. This article aims to present the dynamic behavior of a house as determined through shaking table tests. Based on this experimental multiscale analysis, this paper confirms that timbered masonry structures offer effective seismic resistance; moreover, such a comprehensive analysis helps enhance understanding of the seismic-resistant behavior of timber-framed structures with infill. This paper also aids ongoing development of a numerical tool intended to predict the seismic-resistant behavior of this type of structure.

“…Humbert et al [38,39], presentaron un estudio en dos partes. En la primera, desarrollaron un modelo de elementos finitos calibrado mediante ensayos de laboratorio para determinar los parámetros del modelo histerético que se muestra en la figura 7, mismo que describe el comportamiento no lineal de las uniones S2F, representadas dentro del modelo de elementos finitos por medio de resortes de conexión entre dos nodos.…”

Tras el sismo de Northridge en 1994, mismo que ocasionó daños significativos a las estructuras de madera, la investigación sobre la respuesta sísmica de muros de entramado ligero ha experimentado un notable crecimiento. Este interés se ha extendido más allá de la zona afectada. Autores de países con tradición constructiva en madera han experimentado sobre la geometría de los componentes del muro, la conexión entre el marco y el panel de revestimiento y la implementación de nuevos materiales. En complemento a la parte experimental se han desarrollado modelos numéricos que capturan de forma precisa el comportamiento ante carga sísmica. Este artículo de revisión del estado del arte tiene como objetivo sintetizar las innovaciones y hallazgos encontrados durante la última década, mismos que se detallan en artículos de investigación disponibles en la base de datos ScienceDirect, haciendo de este trabajo una referencia inicial para explorar futuras líneas de investigación en países donde este sistema no ha sido mayormente divulgado. Se ha adoptado la metodología indicada en la declaración PRISMA para dar un adecuado diagnóstico de la información bibliométrica encontrada, adicionalmente se realizaron mapas bibliométricos basados en autores empleando la herramienta VOSviewer. Cabe señalar que en este trabajo se han excluido aspectos de resistencia al fuego u otros factores ambientales. La presentación de los resultados se organiza en función de dos aspectos clave identificados en la literatura: los estudios experimentales y la modelación numérica de muros de entramado ligero.
