[ABSTRACT ]

This study focuses on combining precast concrete system and base isolation technique that could lead to a high- performance seismic resistance structural system. Some previous experimental results on precast concrete modules are presented and discussed. Principles and numerical implementation of base isolation technique are described and presented in details. Analysis of life cycle cost that compares the conventional system and a system that combines precast concrete system and base isolation technique shows promising results. The result from this study is a structural system that has high seismic performance and cost efficiency for certain class of structures and site conditions.
