Course Contents

• Introduction to the concepts of assessment and vulnerability of structures
• Strategies and design for seismic retrofit of buildings
• Overview of regulatory provisions and guidelines relating to interventions and strengthening of
structures. Introduction to KAN.EPE. and Eurocode 8-3
• Estimation of the load-bearing capacity of Reinforced Concrete structural elements
• Materials and techniques for repair/strengthening (RC jackets, FRP etc.)
• Introduction to inelastic methods of analysis of structures

Educational Goals

Upon successful completion of the course, students will be able to:
1. To recognize the forms of failure in existing constructions
2. To understand the concepts of intervention, repair, strengthening, valuation and vulnerability of
structures
3. To be able to choose the appropriate intervention strategy (materials/techniques) for an existing
structure
4. To assess the load-bearing capacity of reinforced concrete structural elements
5. To use the Regulation of Interventions (KAN.EPE.) for the assessment of an existing structure and
the selection of an appropriate intervention

General Skills

– Adapting to new situations
– Decision-making
– Working independently
– Team work
– Working in an interdisciplinary environment
– Project planning and management
– Criticism and self-criticism
– Production of free, creative and inductive thinking

Teaching Methods

Face to face.

Use of ICT means

Παρουσίαση διαλέξεων με χρήση Η/Υ (παρουσιάσεις, φωτογραφίες, βίντεο πειραμάτων, κτλ).

Χρήση της ηλεκτρονικής πλατφόρμας elearning με αναρτήσεις εκπαιδευτικού υλικού σε ηλεκτρονική μορφή και αλληλεπίδραση με τους φοιτητές.

Ανάθεση εργασιών και ηλεκτρονική υποβολή τους μέσω της πλατφόρμας elearning.

Βοηθήματα και παραδείγματα επίλυσης προβλημάτων και ασκήσεων μέσω αυτοματοποιημένων διαδικασιών (jupyter notebooks, excel, κ.α.)

Teaching Organization

Students Evaluation

1. Assignment of tasks aimed at exploring the understanding
of the concepts taught (30%).
2. Final written exam (in Greek) at the end of the semester
(70%).
3. Each student is given the opportunity to review their
written exam and have their mistakes analyzed.
