This International Standard specifies static and cyclic test methods as a basis for the derivation of lateral load resisting parameters which are required in the wind and seismic design of shear walls in timber buildings. This International Standard does not include criteria for parameters which are, at times, stipulated in national standards or building codes. This International Standard can be used to determine those parameters under the following conditions: a) Method I: the boundary conditions are designed to produce mainly the shear response of the wall and ensure that the full shear capacity of the wall is achieved; b) Method II: the boundary conditions are designed to produce mainly the rocking (rigid body rotation of the wall) or combined shear-rocking response of the wall reflecting the intended actual construction details of joints connecting the wall to bottom and top boundaries. This International Standard specifies procedures to ascertain the envelope curves (backbone or skeleton curves) for shear walls subjected to a static or a cyclic displacement schedule.
