Characteristic dynamic traffic load effects in bridges
No full textWhen formulating an approach to assess bridge traffic loading with allowance for Vehicle-Bridge Interaction (VBI), a trade-off is necessary between the limited accuracy and computational demands of numerical models and the limited time periods for which experimental data is available. Numerical modelling can simulate sufficient numbers of loading scenarios to determine characteristic total load effects, including an allowance for VBI. However, simulating VBI for years of traffic is computationally expensive, often excessively so. Furthermore, there are a great many uncertainties associated with numerical models such as the road surface profile and the model parameter values (e.g., spring stiffnesses) for the heavy vehicle fleet. On site measurement of total load effect, including the influence of VBI, overcomes many of these uncertainties as measurements are the result of actual loading scenarios as
they occur on the bridge. However, it is often impractical to monitor bridges for extended periods of time which raises questions about the accuracy of calculated characteristic load effects.
Soft Load Testing, as opposed to Proof Load or Diagnostic Load Testing, is the direct measurement of load effects on bridges subject to random traffic. This paper considers the influence of measurement
periods on the accuracy of soft load testing predictions of characteristic load effects, including VBI, for bridges with two lanes of opposing traffic. It concludes that, even for relatively short time periods, the
estimates are reasonably accurate and tend to be conservative. Provided the data is representative, Soft Load Testing is shown to be a useful tool for calculating characteristic total load effect.Other funderEuropean 6th Framework Project ARCHES (Assessment and Rehabilitation of Central European Highway Structures)au, ke - AS 04/11/201
Surveying the metabolic versatility of biofilm-forming Epsilonproteobacteria: a study into developing ecosystems at extreme environments
No full textAt deep-sea hydrothermal vents, mixing of reduced, super-heated, hydrothermal fluids with cold, oxygenated, seawater creates steep temperature and chemical gradients that support chemosynthetic primary production and rich communities of invertebrates. In 2006, an eruption occurred on East Pacific Rise at 9° 50’N, 104° 17’W. Direct observations of the post-eruptive diffuse flow vents clearly indicated that the earliest colonizers were microbial biofilms. A series of cruises in 2006-07 allowed us to monitor the recovery of the ecosystem. The main objectives of this dissertation are to assess the taxonomic and functional diversity of chemosynthetic bacteria following the eruption, and to correlate it to macrofaunal colonization. To this end, I investigated several microbial biofilms that developed at the bottom of the ocean during exposure to different temperature, redox and biological regimes. Furthermore, I selected pure cultures of vent bacteria representative of these biofilms and designed experiments to investigate their expression of diagnostic genes involved in carbon fixation and respiration. Finally, I used the information obtained from the pure cultures and from metatranscriptomic studies of the vent biofilms to design experiments for the detection of gene transcripts in chemosynthetic microbial biofilm communities collected from deep-sea hydrothermal vents, and to interpret the results. My data showed that the biofilm communities that were exposed to active venting were substantially different from the ones that formed at control sites, and that vent invertebrates could only be detected at the former sites. Furthermore, I found that various members of the Epsilonproteobacteria dominated the chemosynthetic biofilm communities, and that these bacteria fixed carbon dioxide in-situ via the reverse tricarboxylic acid (rTCA) cycle and that they expressed different terminal reductases in response to variable temperature and redox conditions. I demonstrated for the first time that different respiratory pathways (e.g., nitrate reduction, sulfur oxidation/reduction, microaerobic respiration) are expressed simultaneously in chemosynthetic biofilms. In turn, these results imply that the extremely dynamic conditions found at diffuse flow vents, where reduced hydrothermal fluids mix with oxic seawater, provide the biofilm bacteria with a diverse “metabolic menu” in the form of different redox couples that they can use to conserve energy.Ph.

A Multi-hazard Risk Assessment Methodology, Stress Test Framework and Decision Support Tool for Transport Infrastructure Networks
No full textAbstractNatural hazards can cause serious disruption to societies and their transport infrastructure networks. The impact of extreme hazard events is largely dependent on the resilience of societies and their networks. The INFRARISK project is developing a reliable stress test framework for critical European transport infrastructure to analyse the response of networks to extreme hazard events. The project considers the spatio-temporal processes associated with multi-hazard and cascading extreme events (e.g. earthquakes, floods, landslides) and their impacts on road and rail transport infrastructure networks. As part of the project, an operational framework is being developed using an online INFRARISK Decision Support Tool (IDST) to advance decision making approaches, leading to better protection of existing transport infrastructure. The framework will enable the next generation of European infrastructure managers to analyse the risk to critical road and rail infrastructure networks due to extreme natural hazard events. To demonstrate the overarching risk assessment methodology developed in the project, the methodology is demonstrated for two case studies, which comprise portions of the European TEN-T network; a road network in the region of Bologna, Italy and a rail network extending from Rijeka to Zagreb in Croatia. This paper provides an overview of the INFRARISK multi-hazard risk assessment methodology and a brief introduction to the case studies, as the project is currently ongoing. INFRARISK is funded by the European Commission's FP7 programme, Grant Agreement No. 603960. Further information can be found at www.infrarisk-fp7.eu
