“…Method II -Hummel et al [35] Besides the shear deformation of the CLT panel, Method II also considers rotation/rocking of the wall panel due to tensile anchoring and contact, and slip of the wall panel due to shear anchoring. Method II also considers the bending deformation of the CLT panel (Fig.…”

“…Several models for calculating the horizontal displacement of a CLT shear wall, which are based on different assumptions regarding the deformation mechanisms, are available in literature, see for instance [3,5,[13][14][15]. In the next, three of these models are discussed to report a short state-of-the-art.…”

Cross-Laminated Timber (CLT) walls are used in CLT buildings to carry both vertical and horizontal loads. The mechanical behaviour of CLT shear walls for lateral loads is typically assumed to be governed from the base connections, which transfer the horizontal loads from the upper storeys to the foundations. However, in a CLT building, other connection typologies, such as the connection between shear walls and perpendicular walls, can contribute to the mechanical performances of the CLT shear walls. This paper presents a study on the effects of the perpendicular walls on the lateral stiffness of Cross-Laminated Timber shear walls. An analytical model for the calculation of the lateral stiffness of CLT shear walls connected at the base with typical hold-downs and angle brackets and to perpendicular walls by means of wall-to-wall connections is presented. The analytical model is compared with different models taken from the literature and validated against a numerical model developed in SAP2000. The analytical model is used to perform a parametric study in which the geometry and the connections are varied while different assumptions on the mechanical behaviour of the perpendicular walls are considered. Results of the parametric analyses showed that the perpendicular walls increase the lateral stiffness of CLT shear walls. The increase of lateral stiffness depends on the stiffness of the wall-to-wall connections, position and assumption on the behaviour of the perpendicular walls. Results of this study represent a basis for future studies in which the contribution of the perpendicular walls is investigated at building level.

“…Only one global kinematic behaviour, consisting of walls with one centre of rotation for the whole wall, was obtained for all studied situations with window opening.3.2.2. Wallner-Novak et al (2013)The Wallner-Novak et al (2013) approach takes into account the same contributions asHummel et al (2016) method, with only a minor change in the determination of the shear stiffness of the CLT panel due to a lower shear modulus. The overall displacement is computed using panel bending and shear, as well as sliding and rocking deformation contributions: in Eq.…”

Experimental verification of analytical strength and deformation methods for single and multi-panel nailed CLT shear walls

Cross-laminated timber (CLT) is becoming a feasible alternative as structural material for midand high-rise buildings. Although CLT walls are appropriate for resisting lateral loads from wind and earthquakes, the current provisions in the Canadian Standard for Engineering Design in Wood lack analytical expressions for estimating their resistance and deflection.In this thesis, the performance of nailed single and couple CLT shear walls is investigated by comparing UNBC test data with the strength and stiffness predictions using analytical proposals. Four methods are considered: Method A (Casagrande et al. 2017), considers the minimum strength value of the hold-down and the vertical fasteners; Method B (Shahnewaz et al. 2019), which accounts for the rocking resistance of all connectors; Method C (Masroor et al. 2020) which accounts for the bi-axial behaviour of connectors; and Method D (Nolet et al. 2019) which describes the elastic-perfectly plastic behaviour of CLT shear walls while neglecting the bi-axial behaviour of brackets.
