    Pres-Lam technology aims to allow timber to stand alongside concrete and steel as a material of choice for multi-storey frame structures. It combines Laminated Veneer Lumber (LVL) structural members post-tensioning and energy dissipation devices. This enables the design of buildings are easier to repair, and able to be reoccupied quickly following earthquakes. This thesis investigates beam column joints for post-tensioned timber frame buildings, with the aim of providing design and detailing guidance to building designers. A full scale experimental campaign was undertaken. This involved two options for joint armouring and three types of dissipation devices. The results of full scale experimental testing of beam column joints are shown, with a discussion on constructability, performance and reparability. Numerical and analytical models were developed based on the results of testing. These were used to investigate joints as part of overall structural systems as well as localised behaviour. Several buildings utilising this technology have already been constructed and, it is hoped that this research will give designers greater confidence in the system when designing future structures.
