Timber-frame panel buildings have a very specific composition where the main challenge represent mechanical fasteners, which are unable to provide a fully rigid connection. The stiffness of the timber-framed walls is thus largely dependent on various factors that influences its stiffness, such as the bending and the shear flexibility of the composite wall element, the flexibility of the fasteners between the timber frame and the sheathing board along with the flexibility of the tensile and compressive support. Despite the fact that these contributions to the stiffness of the timber-framed walls are not negligible, they are not considered in Eurocode 5 standard for design of timber structures. The current paper analyses the contribution of the tensile support and presents the experimental and analytical study of inter-storey hold-down connections in timber-framed panel construction system. Experimental tests are performed for two different hold-down connections appropriate for connecting timber-framed walls from the upper floor through the ceiling to the timber-framed-walls of the lower floor. Experimental results show that hold-down connections do not provide a rigid support conditions for the timber-framed walls and that their flexibility should be taken into account when calculating the overall horizontal stiffness of the timber-framed walls. Therefore, an analytical expression for determination of the stiffness of the hold-down is suggested for the hold-down connection with perforated strap. The formula can be used for analytical calculation of the stiffness of the timber-framed walls by taking into account the stiffness of the tensile support when a tested hold-down anchor is used.
