Mass Plywood Panels (MPP) are a new mass timber material produced in Oregon. This panelized product shows promise as a wall system for structures, however, for it to be used in seismic prone areas (such as the Northwest) the response of the product to cyclic loads must be understood. Panelized Mass Timber wall systems generally resist load in two ways, the first is through connections that resist the shear along the bottom of the wall and/or the overturning trying to push over the wall. The second is crushing at the bottom corners of the wall to resist overturning. This crushing was investigated using full scale, 4’ by 8’ panels subjected to cyclic loading with differing base conditions. Understanding the response of different base conditions, each representing a different design ideology, will allow for the best utilization of MPP walls, introducing more flexibility of material choices for engineers and architects looking to design wood structures. The wall response and observations from testing will be discussed, as well as comparisons between base conditions and further investigation needed to optimize wall performance.
