| Zusammenfassung |
| Decision is an element in the risk management process. In this paper the way
how science can help in decision making and implementation for retrofitting
buildings in earthquake prone urban areas is investigated. In such
interventions actors from various spheres are involved. Their interests
range among minimising the intervention for maximal preservation or
increasing it for seismic safety. Research was conducted to see how to
facilitate collaboration between these actors. A particular attention was
given to the role of time in actors' preferences. For this reason, on
decision level, both the processural and the personal dimension of risk
management, the later seen as a task, were considered. A systematic approach
was employed to determine the functional structure of a participative
decision model. Three layers on which actors implied in this multi-criteria
decision problem interact were identified: town, building and element.
So-called 'retrofit elements' are characteristic bearers in the
architectural survey, engineering simulations, costs estimation and define
the realms perceived by the inhabitants. This way they represent an
interaction basis for the interest groups considered in a deeper study. Such
orientation means for actors' interaction were designed on other levels of
intervention as well. Finally, an 'experiment' for the implementation of the
decision model is presented: a strategic plan for an urban intervention
towards reduction of earthquake hazard impact through retrofitting. A
systematic approach proves thus to be a very good communication basis among
the participants in the seismic risk management process. Nevertheless, it
can only be applied in later phases (decision, implementation, control)
only, since it serves verifying and improving solution and not developing
the concept. The 'retrofit elements' are a typical example of the detailing
degree reached in the retrofit design plans in these phases. |
