What we'll cover
- Basic understanding of base isolation Why decoupling a building from ground motion works: period shift, reduced floor accelerations and inter-storey drift, and where base isolation makes sense.
- Types of base isolators Elastomeric bearings (low-damping rubber, high-damping rubber, lead-rubber) and sliding systems (flat sliders, friction pendulum), with how each provides flexibility and damping.
- Deriving the dynamic equation of a base-isolated system Building the two-degree-of-freedom model step by step, from free-body diagrams to the coupled equations of motion.
- Questions and discussion Open Q&A at the end of the session.
