Abstract

Past severe earthquakes imposed considerable life and financial loss to earthquake-prone countries. In the 2011 Christchurch earthquake, most of the buildings designed for the code requirements performed as expected and saved lives. However, a big financial loss was imposed on the economy to repair and rebuild the damaged buildings. Therefore, the importance of earthquake resiliency and a need to shift to a more resilient design philosophy known as Damage Avoidance Design (DAD) became clear. Researchers suggested that cost-efficient Damage-Avoidance structural systems should be used in seismic resisting structures to achieve more resilient designs. Hence, developing new systems is an important part of this movement. The scope of this research is to develop a cost-efficient damage-avoidance system that can be used in a variety of applications. In this study, an existing seismic device is improved, a new device is developed and patented and the application of these devices in a structural system is studied and experimentally verified. The outcome of this thesis can be used to design seismic damage-avoidance devices and structures.
