Plastic models for analysis of fully anchored light-frame timber shear walls

Experimental results on the role of sheathing-to-frame and base connections of a European timber framed shear wall

“…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].…”

A predictive analytical model for the elasto-plastic behaviour of a light timber-frame shear-wall

“…In [17] a plastic model is proposed for the analysis of fully anchored light frame-timber shear-walls applying the upper and lower bound methods and evaluating the plastic strength of a fully anchored wall. The expressions proposed in [10], characterised by linear relationship to the sheathing-to-fastener deformation e n and to the anchorage connection deformation d a , might be used also in the non-linear range since the displacement of the wall due to these two contributions was obtained by geometrical considerations on the deformation of the wall.…”

Mathematical modelling of timber-framed walls using fictive diagonal elements

“…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. According to Källsner and Girhammar [21], the plastic approach to the analysis of fully anchored light-frame timber shear walls was presented, where the models are based on the assumption of plastic load-slip relations for the sheathing-to-framing joints. Two simplified design procedures are given in Eurocode 5 [7] in order to determine the load-carrying capacity of the wall diaphragm being referred to as Method A and Method B, respectively.…”
