Course description and aims

Dynamic characteristics of dampers, as well as the structures combining dampers, braces or other supporting members will be explained and their design and analysis methods are discussed. The structure is defined as the damper-installed structure. In addition, base-isolated structures and their dampers are also explained. Commonality and difference between both structures are explained and a unified theory to characterize/contrast their performance will be learned.

Student learning outcomes

Mastering the methods to analyze, design, and evaluate both damper-installed structures and base-isolated structures.

Keywords

Passive control dampers, frame types, analysis method, design method

Competencies that will be developed

✔ Specialist skills Intercultural skills Communication skills ✔ Critical thinking skills ✔ Practical and/or problem-solving skills
