This article describes tests investigating a feasible source of passive damping for post-tensioned glue laminated (glulam) timber structures. This innovative structural system adapts precast concrete PRESSS technology (Priestley et al. 1999) to engineered wood products combining the use of post-tensioned tendons with large timber members. Current testing is aimed at further improvement of the system through additional energy dissipation. Testing has favourably compared glue laminated timber (not previously implemented in this way) with laminated veneer lumber (LVL) used in New Zealand. After initial benchmark testing with post-tensioning only, a simple, minimally invasive and replaceable type of hysteretic damper was added
