“…14d). This result is consistent with the value that can be analytically calculated by means of the models found in literature [5,46]. Consequently, the experimental results may be an effective tool for the verification of the analytical and numerical models published in literature when NRb ring nail are used.…”

“…Finally, by assuming that frame studs and the particleboard panels behave elastically up to the wall failure and that the frame joints act as hinges [5,6], the total displacement (D tot ) can be evaluated as the sum of five components due to (i) the rigid rotation of the wall (D H ), (ii) the wall base sliding (D AB ), (iii) the relative panel-frame rotation (D N ), (iv) the shear deformation of the sheathing wall (D c ) and (v) the flexural deformation of the frame related to the axial deformation of the frame studs (D EA ), hence:…”

“…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].…”

“…For example, Källsner and Girhammar [20] developed an elastic analysis model for fully anchored sheathed wood frame shear walls. The model can be applied to statically loaded shear walls to evaluate the horizontal load-bearing capacity and the horizontal displacements of the wall, as well as the slip in the sheathing-to-timber joints.…”

a b s t r a c tThis paper presents mathematical modelling of timber-framed wall where a braced frame with one fictive diagonal is used. The model is suitable for analysis of lateral loads on the structure. Its advantage compared to other models is its simplicity, the fact that it is easy to use in practise, and its suitability for use with simpler and cheaper programs for static and dynamic analysis. Further numerical calculations were performed, which showed good approximation with experimental studies and with the finite element method. The Tower 6 program for static and dynamic analysis has been used to model timber-framed walls. Appropriate stiffness of timber-framed wall is obtained by varying the cross-section of the fictive diagonal. Because the cross-section of the fictive diagonal is directly connected to the analytical calculation of the stiffness of the timber-framed wall, this model is also able to factor in different spacing distance, different sheathing boards, the appearance of tensile cracks in a sheathing board, as well as walls with glazing or openings.

“…This was mainly done by using light timber framing systems with sheathing of plywood or other materials. While providing significant ductility, those systems generally highlight significant stiffness and strength degradation (Gupta et al, 1987;Stewart, 1987;Deam, 1996;Karacabeyli et al, 1999;Durham et al, 2001;Filiatrault et al, 2009;Källsner et al, 2009;van de Lindt et al, 2010;Kirkham et al, 2013).…”

Development and Testing of an Alternative Dissipative Posttensioned Rocking Timber Wall with Boundary Columns

The unbonded post-tensioned rocking and dissipative technology was first developed as the main outcome of the PRESSS (PREcast Seismic Structural Systems) Program in US.After the first developments and significant refinement, the technology was extended to steel and, more recently, timber structures. The timber version, referred to as Pres-Lam (Prestressed laminated) system can be either implemented for timber walls (single or coupled) or frames or combination of the above, with unbonded post-tensioning and supplemental dissipation devices.In unbonded post-tensioned dissipative wall systems a combination of re-centering capacity and energy dissipation leads to a "controlled rocking" mechanism which develops a gap opening at the wall base. This generates an uplift displacement which is transferred to the floor diaphragm. This vertical displacement incompatibility can represent a potential issue if the connection detailing between floor and lateral resisting system is not designed properly.The same issue can be mitigated by adopting an alternative configuration of the rocking/dissipative wall system, based on the use of a column-wall-column post-tensioned connection. This concept, originally proposed for precast concrete walls and referred to as PreWEC (Prestressed Wall with End Column), has been extended and adapted to posttensioned timber structures and validated through experimental testing.
