STEP-Strategies and Tools for Early Post Earthquake Assessment Fabio Germagnoli EUCENTRE Pavia, Italy Lubjana, 25 September 2008
Short Course on Post-Earthquake Buildings Safety and Damage Assessment
STEP has been selected under the Call for proposals 2006/C 176: 'Pilot Projects on civil protection cross border co-operation in the fight against natural disasters'
Explore the possibility to integrate conventional post earthquake on field actions (inspection, visual assessment, etc.) with advanced assessment procedures
Create a prototype of evaluators network
Organize events to test the prototype and train assessors group on the use of the network
Improve assessment efficiency specially for applications in critical cases

STEP – Objectives of the project
1. Review of the assessment techniques - Experimental methods for the evaluation of geometrical characteristics, mechanical properties and structural details (level of knowledge of the structure as defined in EC8 and other European code of practice) and numerical analysis for vulnerability assessment will be considered.
2. Design and construction of a Mobile Unit prototype (MU) – The results of the previous review will orient the design and construction of a Mobile Unit (mobile experimental laboratory) properly equipped to perform experimental tests to improve structural level of knowledge and to perform some analytical estimates of the seismic vulnerability.
3. Design of a Coordination Unit (CU) - A special unit with coordination function will be designed and developed to work with MU(s). Fast and reliable wireless connection (Satellite for example) will be implemented to guide MU(s) on field actions, to exchange useful information (shared and used later with other experts working in remote laboratories;
4. Guidelines for optimized use of CU and MU pre earthquake phase to increase – The most important use of coordinated Cu and MU(s) is related to emergency periods, but these resources could efficiently be used in vulnerability knowledge particularly for those buildings with special function in Civil Protection ambit. Guidelines for coordinated employment both during post earthquake emergency and in pre-shake phase will be developed and provided;
5. Harmonization of cross border actions methods. – The advanced procedures developed in this project will be integrated into traditional Civil Protection approaches based on visual inspections and simplified evaluation with vulnerability checklists. Training courses and in field practical application involving several Civil Defence European Institutions will be prepared with the main scope of increase the new assessment tools knowledge and create common intervention procedures using both traditional and advanced assessment

Procedural point of view: explore the possibility to have one european mixed team and several trained country teams using the same methodologies
Short Course on Post-Earthquake Buildings Safety and Damage Assessment
Culture /language In every country local authorities are in charge of the safety assessment, according to the fact that, during the response to disaster situations, the lowest ranking level of government is always in charge. In case of destructive earthquakes, when local resources are no more sufficient, a high level management is activated, up to the State level. International intervention is not common in safety and damage assessment, due to differences in building types, forms, language and concepts.

POLITICAL INFLUENCES
In Japan the aim of the damage assessment is to evaluate the long term use of the buildings. The result of the evaluation is a suggestion of the owner of the building concerning the repair, the retrofit or the demolition. In Italy the main purpose is to support the usability classification and, at the same time, to estimate the overall amount of direct economic loss, in order to establish the need for reconstruction. The decision on long term use of building is postponed to an engineering evaluation in the reconstruction process. In Greece damage survey is not performed, because financial contribution are established on the basis of the usability classification. In Turkey the damage classification is performed to assign financial contribution to each Building.
