Introduction to research university projects Disaster prevention: up-to-date engineering methods Prof. János Józsa Head, Department of Hydraulic and Water Resources Engineering Vice-Dean for Science, Faculty of Civil Engineering Cooperation Platform of Central and East European Metropolitan Universities of Technology Meeting Budapest, June 12-13, 2014
Outline of Research Framework 6 Four main themes Flooding Earthquake impacts Disastrous environmental pollution Industrial security, fire and explosion All relevant in disaster prevention and management, with a lot of links to each other
Some relevant past and ongoing research projects
Rivers and floodplains Natural conditions Floods leading to disaster Man-made damming
Sajókeresztúr Sajó Szirmabesenyő Flood-induced rural and urban inundation
MISKOLC Flood-induced rural and urban inundation
Modelled inundation for disaster prevention planning
What if a thousand years return period flood wave arrives in River Danube at Budapest
Industrial disastrous floods and their impact
Red mud spill in Hungary in 2010
Computer simulated spill and inundation process
Impact assessment of various prevention measures
Soil mechanics aspects of earth dam construction: Pore water changes in the construction and operation period
Lab and computer simulated drift of solid bodies by floodwaves
Impact of dam break flood waves on buildings investigated in lab by PTV analysis
Downstream environmental impact of the red mud spill
Height: 48 m, cross-section: steel box(~2 x 3 m) Span (arch) : m Total length: 1780 m Bridges to resist earthquakes Pentele bridge over Danube in Hungary
Pylon height: 100 m Span (cable-stayed bridge) : 300 m Total length: 1862 m Bridges to resist earthquakes Megyeri bridge over Danube in Hungary
A modal shape analysis for earthquake resistant design
Finite element model ANSYS, explicit dynamic analysis harmonization of the parameters of FE model and real aircraft simplified aircraft geometry for parametric studies target structure: circular shell aim: determination of important input parameters broken elements are deleted from the calculation Full-scale test: Sugano et al. 1993, New-Mexico F4-Phantom fighter velocity: 215 m/s 7×7×3.66 m reinforced concrete block aircraft was totally crushed (debris dispersed) penetration did not occur (concrete cover was damaged) aircraft crushed only at the cross-section adjacent to the target Full-scale impact test Target damage Last example: Aircraft crash into NPP containment wall
HORIZON2020 outlook Two relevant submitted applications: PFM-WATER – Monitoring of Particle-laden Fluxes for more efficient use of Water 21 partners from all over Europe, leading by Bologna DREAM-CO – Danube River Research and Management Coordination Action 34 partners, leading by BOKU, Vienna
