摘要：
This paper presents a predictive analytical model for the elasto-plastic behaviour of a light timber-frame wall under horizontal loading. The possibility to represent the total force carried by all fasteners (allowing for their sequential yielding) in one nonlinear spring is shown to be a key benefit. The development of this spring was investigated via a parametric study in which the variables were the sheathing panel aspect ratio and the fastener spacing. By developing equivalent springs for the other components, a rheological model for elasto-plastic behaviour of a sheathed timber-frame as function of the mechanical properties of connections was also defined.
