“…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.

“…Concentrating non linear phenomena in joints for studying the response of modern timber-framed structures under quasi-static or dynamical load is very classical (see Dolan 1989, White and Dolan 1995, Kasal, Leichti, and Itani 1994, Humbert et al 2014, Boudaud et al 2015 since dowel-type joints are generally used. In the present study, dissipative phenomena are due to yielding in joints but also to complex phenomena (cracking, friction) occurring in the earth infill.…”

“…Such a modeling approach is classical for timber-framed structures (Andreasson, Yasumura, and Daudeville 2002, Yasumura et al 2006, Richard et al 2002, Xu and Dolan 2009. Both the nonlinearity in the diagonals and in the steel strip are described by a non linear constitutive law (Humbert et al 2014). This model allows to describe the metallic timber-timber connection taking into account the damage under reverse loading, which means a strength reduction.…”

Due to their seismic resistance, traditional timber-framed structures with masonry infill suffered little damage during recent earthquakes. Moreover, timber-framed structures can be built with reduced costs thanks to the use of locally available materials such as wood, stone, and earth. Based on an experimentally validated numerical simulation for a one-story house, the seismic resistance of a similar two-story house is investigated. A simplified Finite Element Model with linear and nonlinear truss elements is proposed to analyze the seismic resistance of a two-story building. Nonlinear hysteresis constitutive laws are defined only for two majorcomponents of the structure which are assumed to be representative of the global structure behavior: diagonal X-crosses (concentrating the interaction with the infill material) and steel strip connections. These kinds of structures have been overlooked due to a lack of knowledge of their potential behavior in seismic prone area and a lack of building codes and standards for their own design. To promote them, a failure criterion, that might easily be used in engineering studies, is required. This article proposes a simple criterion based on Eurocode 8 to quantify the seismic resistance of one-and two-story houses. The simulation shows that, even in case of high intensity ground motion, the two-story building should not be collapsed. This study may help at designing twostory timber-framed structures in seismic prone areas for (re)construction projects.

“…As a result, the hysteretic behavior of timber frame constructions is governed by the local behavior of sheathing-to-frame connections, angle bracket and hold-down connections, which are responsible for the structure's dissipative capacity. Among these joints, the behavior of the local joint between the timber frame and sheathing panel http is one of the most relevant as confirmed by the expressions of main standards [1][2][3][4], by analytical models [5][6][7] and by numerical Finite Element Modelling of wood-frame walls [8,9].…”
