The European Commission has approved and financed an ErasmusMundus Masters on Earthquake Engineering and EngineeringSeismology (MEEES), coordinated by the ROSE School andfeaturing also the participation of the University of Grenoble JosephFourier (France), the University of Patras (Greece) and the ImperialCollege of London (UK), as project partners, as well as of JointResearch Centre (Ispra, Italy) and the Italian Institute for Geophysicsand Vulcanology (Italy) as satellite participants. Within theframework of this prestigious Erasmus Mundus programme, whichaims to enhance quality in European higher education and topromote intercultural understanding through co-operation with thirdcountries, a relatively large number of scholarships are available forboth non-European as well as European students. Interestedapplicants are invited to visit the MEEES website (www.meees.org)for detailed information and instructions on financial conditions andapplication procedures.

In addition to ROSE School students, a maximum of 20 externalparticipants may be accepted to the course, under the payment of a500€ fee. Special financial conditions are, however, in place forUniversity researchers or students, to whom a fee of not more than300€ is requested.

Those wishing to attend the Course should contact the ROSE SchoolSecretariat.

ROSE SCHOOL European School for Advanced Studies in Reduction of Seismic Risk

• THE SHORT COURSES AT ROSEIn addition to its masters and doctorate teaching programmes, the EuropeanSchool for Advanced Studies in Reduction of Seismic Risk (ROSE) organisesalso a number of short courses, within its general aim of providingadvanced training in the field of earthquake engineering. These shortcourses are characterised by their brief duration (1-2 weeks), with respectto the traditional modules taught at the School (4-5 weeks), and feature afocus on relatively specific structural/seismic engineering topics (rangingfrom basic to advanced issues). The short courses are oriented towards MScand PhD students, as a complement to their graduate education, andtowards research engineers, designers and practitioners working in the fieldof structural and earthquake engineering, as an opportunity to expand andupdate their professional knowledge.

• OBJECTIVES OF THE COURSEThe main objective of the course is to introduce structural engineers to thebasic principles of passive supplemental damping and seismic isolationsystems and to their implementation into real structures.

An introduction on the basic earthquake engineering principles and energyformulation needed to understand the impact of different supplementaldamping and isolation techniques on the performance of structures is firstprovided.

The focus is then set on theoretical and applied knowledge on varioussupplemental damping and seismic isolation systems that havedemonstrated potential at raising the performance of buildings and bridgesunder earthquake ground motions while keeping construction costsreasonable.

For each of the supplemental damping and base isolation systems such ashysteretic dampers, viscous and visco-elastic dampers, self-centeringsystems, tuned-mass dampers, elastomeric, lead-rubber, metallic and slidingbearings, the physical behaviour, analytical modelling, experimentalinvestigations and practical implementations are presented.

Design strategies and methods are also presented for each of thesupplemental damping and seismic isolation systems. Finally, two sampleprojects are described: the seismic isolation of a complex new structure andthe retrofit of an existing steel moment-resisting steel frame using variouspassive supplemental damping devices.

The course is fully organised by Dr C. Christopoulos, from the Universityof Toronto, Canada, who will be responsible for all lecturing activities. Inaddition, it is also noted that a textbook recently published by the IUSS Press("Principles of Passive Supplemental Damping and Seismic Isolation," by C.Christopoulos and A. Filiatrault) covers the material that will be taught duringthis course, and is available from the IUSS Press website (www.iusspress.it).
