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


Objectives of the project


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

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


- 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.
