Objectives

According to the above goals, the project lasting 42 months (may 2016-october 2019) is articulated with the following Research and Innovation Project Objectives (PO):

  • PO1: Establish an EILD Risk / Resilience Assessment and Improvement Framework based on a common understanding amongst the consortium partners and relevant external stakeholders (expert/advisory groups), identifying physical, social, economic and environmental vulnerability and the appropriate mitigation strategies with the wider community context.
  • PO2: Develop a European liquefaction hazard map (macrozonation) and identify, based on the analysis of four european case studies (in Italy, Portugal, Slovenia and Turkey) a methodology to perform localized assessment of liquefaction potential (microzonation), to be subsequently used to update the macrozonation framework.
  • PO3: Develop new simplified methodologies and define a protocol for the vulnerability assessment of structures and infrastructures to EILDs by establishing guidelines for the application of soil characterization and liquefaction risk assessment and performing liquefaction fragility analysis of interacting earthquake-soil-structure system.
  • PO4: Comprehensively analyse, with the aid of seismic centrifuge tests and two full scale field trials, a selection of state of the art liquefaction mitigation techniques suitable for small to medium sized ‘critical’ infrastructures (“lifelines” and low-rise structures) which could have aggregated impacts of greater significance than initially perceived during an EILD.
  • PO5: define vulnerability, resistance, resilience and adaptive capacity models applicable across the varying regions of Europe by developing multi-criteria assessment methodology, performance metrics and a built asset management (BAM) life cycle model.
  • PO6: Integrate all the previous methodologies into a LIQUEFACT Reference Guide (LRG) and a user friendly software application toolbox, working at individual structure/infrastructure or at regional/city level, wherein engineers or stakeholders involved in the design and implementation can be guided to assess the feasibility and cost-benefit of certain liquefaction mitigation techniques or compute the socio-economic impacts of risk reduction and resilience improvement strategies.
  • PO7: Validate the proposed LRG framework with a retrospective simulation of past EILD events and bring together the previous knowledge into guidelines enabling the task groups revising the EU Structural Eurocodes to produce technical standards for new and existing buildings where the potential EILD risk is identified and resilience measures incorporated.
