SemesterAutumn Semester 2022
LecturersM. Vassiliou
Periodicityyearly recurring course
Language of instructionEnglish

AbstractThis course will cover the analysis and design of isolation systems to mitigate earthquakes and other forms of vibrations. The course will cover:
1. Conceptual basis of seismic isolation, seismic isolation types, mechanical characteristics of isolators.
2. Behavior and modeling of isolation devices, response of structures with isolation devices.
3. Design approaches and code requirements
ObjectiveAfter successfully completing this course the students will be able to:

1. Understand the mechanics of and design isolator bearings.
2. Understand the dynamics of and design an isolated structure.
Content1. Introduction: Overview of seismic isolation; review of structural dynamics and earthquake engineering principles. Viscoelastic behavior.
2. Linear theory of seismic isolation
3. Types of seismic isolation devices - Modelling of seismic isolation devices – Nonlinear response analysis of seismically isolated structures in Matlab
4. Behavior of rubber isolators under shear and compression
5. Behavior of rubber isolators under bending
6. Buckling and stability of rubber isolators
7. Code provisions for seismically isolated buildings
Lecture notesThe electronic copies of the learning material will be uploaded to ILIAS and available through myStudies. The learning material includes: reading material, and (optional) exercise problems and solutions.
