Learning Outcomes

After the successful completion of the above course, the student will:

  • Be able to understand the causes of seismic damage and recognise the relevant deficiencies of reinforced concrete (RC) and masonry structures.
  • Have the basic knowledge to estimate or evaluate the seismic capacity of the above structures, using approximate or more accurate methods, according to Eurocode, Greek and International Standards.
  • Know and be able to choose appropriate strategies for the redesign of existing structures.
  • Know the materials and technologies of intervention for repair or strengthening.
  • Be aware of the models simulating the contact between old and new materials and other models, provided in European and Greek Standards, to enhance the seismic capacity of RC or masonry elements either by increasing their ductility or by increasing their strength.
  • Be able to design and evaluate the capacity of repaired or strengthened RC and masonry components, depending on the selected intervention.

Module general description:

Assessment of Seismic Damages, Repairs and Strengthening of Reinforced Concrete Buildings
The problem of seismic vulnerability of existing structures and the importance of their seismic assessment and strengthening. Seismic damages of reinforced concrete buildings. Damage in beams, beam-to-column connections, ordinary and short columns, shear walls and staircases. Seismic assessment of existing structures by inspection and by calculations based on either forces or deformations. Strategy for the re-design of seismically damaged structures. Technologies for repair and strengthening. Special concretes, polymeric glues, repair plastering, sheets of steel or fiber-reinforced polumers, anchors, etc. Bases for the re-dimensioning of members. Design of steel connectors (bolts and anchors). Welding of new reinforcing bars. Design of old-new concrete interface. Repair and strengthening of beams, columns, shear walls, beam to column connections and foundations of reinforced concrete buildings damaged by earthquakes.

Assessment of Seismic Damages, Repairs and Strengthening of Traditional and Monumental Buildings
Basic principles for the repair, strengthening and restoration of traditional and monumental buildings made of (mainly) masonry or wood. Methods of analysis and design as influenced by the law governing traditional and monumental buildings. Mechanical characteristics of building materials (stone, brick, mortar, wood). Traditional ways of analysing, designing and building these buildings. Typical damages in masonry walls under in-plane or lateral seismic loads. Assessment of damages and methods for repair, strengthening and restoration. Description of a typical repair, strengthening and restoration methodology for a monumental masonry structure.

Subjects covered:
1. Seismic Damage Evaluation, Repair and Strengthening of Reinforced Concrete Buildings
2. Seismic Damage Evaluation, Repair and Strengthening of Traditional and Monumental Buildings

Teaching Method: Distance education with six Contact Sessions held at weekends during the academic year

Evaluation: Completion of five written assignments during the academic year, the average grade of which constitute a 30 percent of each student's grade, if a pass is obtained in the final or repetitive examination. Final exam grades constitute a 70 percent of the students' final course grade. More information is available
