  4. 4. CA‘REDIVIVUS project100th Anniversary of the 1906 San Francisco earthquake Introduction Valuation of existing buildings instead of design of new buildings Challenge in earthquake prone countries More research on masonry than on RC Concrete in France and Germany Concrete in Italy, Greece, Romania, Portugal Multidisciplinary decision Conservation of heritage housing buildings

  7. 7. CA‘REDIVIVUS project100th Anniversary of the 1906 San Francisco earthquake Nr. Objective Interest groups 1 - advance in earthquake engineering - improving understanding of earthquake impact on the physical, social, economic and cultural environment - developing comprehensive measures for preventing earthquake loss Multidisciplinary 2 an algorithm for optimisation of retrofit measures - 3 decentralised decision model for actors involved from: - geophysics (engineering seismology) - (structural) engineering - economy (investment efficiency) - sociology (consideration of user issues) Interdisciplinary 4 ? applicability of retrofit methods which reduce demand (active devices on frame braces) Interdisciplinary architecture engineering 5 framework for integral planning (economic and engineering aspects regarded from incipient planning phases) Interdisciplinary architecture engineering economics 6 solving contradictions between the objectives of single actors in the retrofit implementation strategy through decision system customisation Multidisciplinary 7 comprehensibility of the measures analysed: inclusion into the integral planning scheme near the flow in the physical implementation of the retrofit system of a flow for the education of the population which has to support the measures (spread from pilot projects to „routine‟ wide ones) architecture urbanism sociology 8 investigation of the support possibilities by political and economic environment: existing programmes -

  9. 9. CA‘REDIVIVUS project100th Anniversary of the 1906 San Francisco earthquake Nr. Objective Method Instruments 1 improving understanding of earthquake impact - public presentation - react to feedback on findings on the architectural, structural, geophysical, social and economic aspects of retrofitting historic concrete buildings - active participation, co-organisation of conferences - publication in reviewed manner - web dissemination of results 2 algorithm for retrofit measures optimisation parametrical study FEM 3 decentralised decision model modularisation of a collaborative decision model taking into account non-measurable criteria pair wise comparison method used in investigation of decision making on different levels; multiobjective systems in urban/building scale transition 4 applicability of retrofit methods - insights documentation training literature and internet based research lectures and assisted exercises. 5 framework for integral planning an example retrofit design model project for the integral planning and defining its steps exercise 6 solving contradictions between the objectives of single actors a basis system to administrate modules on the different detail levels in the urban strategical planning ? suitability of different computer tools (GIS, spread sheets, multimedia …) 7 „comprehensibilisation‟ of the measures analysed steps are foreseen in the „educational flow‟, so the information circuit gets into a second phase: - determine research directions - determine means for accessibilisation of information - investigation of consulting and participation means - education - create public ideas - connection between education and research. database for - public presentation - urban/building level navigation - feedback 8 ? change is supported by political and economic environment documentation, conference organisation activity “Natural Hazards Impact on Urban Areas and Infrastructure”; similar events.
