Learning Objectives

After the successfully completing the course, the students will:

  1. be able to seismically design a building to the seismic code.
  2. be able to apply the performance-based design philosophy.
  3. be able to seismically design a structure using nonlinear analysis methods.
  4. understand the fundamentals of seismic reliability analysis through fragility curves.
  5. be able to design structures considering soil-structure interaction.

Teaching Methods

Teaching methods Class lectures and tutorials
Teaching media " Presentation over the blackboard " Power Point slides
Laboratories NO
Computer and software use Excel, Matlab and structural analysis packages
Problems - Applications Class tutorials and home assignments. Specifically: Class tutorials will be presented in class and solved with the aid of the teaching staff. The tutorials will be handed in at the end of class. Home assignments will be also required in order to assist understanding in depth the underlying concepts.
