ABSTRACT
SCOPE OF LESSLOSS SP5
LESSLOSS SP5 is on In-situ Assessment, Monitoring and Typification of Buildings and
Infrastructure. It focuses on innovative and state of the art methods for the assessment
of the following important existing structures:
- Buildings whose integrity during earthquakes is of vital importance for civil
protection, e.g. hospitals, fire stations, power plants, telecommunication facilities,
etc. (importance class IV according to EN1998-1:2005)
- Bridges of critical importance for maintaining communications, especially in the
immediate post-earthquake period, bridges where failure is associated with a large
number of probable fatalities and major bridges, where a design life greater than
normal is required (importance class III according to EN 1998-2:2005)
- Buildings whose seismic resistance is of importance in view of the consequences
associated with a collapse, e.g. schools, assembly halls, cultural institutions, etc.
(importance class III according to EN1998-1:2005)
- Industrial facilities, where secondary risks exist, e.g. the risk of release of toxic
and/ or explosive materials
- Cultural heritage
It is of high importance, that these structures remain greatly undamaged and serviceable.
If necessary, their earthquake resistance has to be increased based on the results of
assessment. Normally the highest degree of knowledge is necessary to afford safety
assessments for such structures. It is attained by setting a detailed, often 3D, structural
model, based on careful surveys updated by using measured dynamic properties. It is one
of the basic ideas of SP5 to integrate experimental techniques into the assessment
procedure, which is an advantage one has in the case of existing buildings.
If such investigations are carried out in the pre-earthquake phase, measures for seismic
upgrading can be undertaken in due time. In the post-earthquake phase these
investigations enable the determination of the remaining safety and the serviceability,
especially if mathematical models representing the previous status of the structure were
elaborated before, which may in general already be characterized by damage). Hence, the
task damage detection is crucial within LESSLOSS/ SP5.
The most important product of SP5 is the European Manual for in-situ Assessment of
the Earthquake Resistance of Important Existing Structures. The manual provides also an
overlook over literature useful for practical application. Many criteria and tools are
already existing, but too less evident and therefore not accessible to the designers/
practitioners.
The Manual consists of Part I: Training and Part II: Practical Application. The personnel
which has to be trained should have a fundamental education in structural dynamics and
earthquake engineering (SD&EE). But the most important chapters of SD&EE, which
are relevant for structural assessment, are summarized in an adequate, illustrative way in
the Training Manual. The basis for the manuals are the deliverables D19, version 2007,
D19A, version 2006 and D20, version 2007 of LESSLOSS SubProject SP5. Especially in
the Application - Part the procedures are demonstrated via case studies.
