Zusammenfassung |
The design of efficient hydrological risk mitigation strategies and their
subsequent implementation relies on a careful vulnerability analysis of the
elements exposed. Recently, extensive research efforts were undertaken to
develop and refine empirical relationships linking the structural
vulnerability of buildings to the impact forces of the hazard processes.
These empirical vulnerability functions allow estimating the expected direct
losses as a result of the hazard scenario based on spatially explicit
representation of the process patterns and the elements at risk classified
into defined typological categories. However, due to the underlying
empiricism of such vulnerability functions, the physics of the damage-generating mechanisms for a well-defined element at risk with its peculiar
geometry and structural characteristics remain unveiled, and, as such, the
applicability of the empirical approach for planning hazard-proof
residential buildings is limited. Therefore, we propose a conceptual
assessment scheme to close this gap. This assessment scheme encompasses
distinct analytical steps: modelling (a) the process intensity, (b) the
impact on the element at risk exposed and (c) the physical response of the
building envelope. Furthermore, these results provide the input data for the
subsequent damage evaluation and economic damage valuation. This dynamic
assessment supports all relevant planning activities with respect to a
minimisation of losses, and can be implemented in the operational risk
assessment procedure. |
