(2014-2018) Structural Health Monitoring is good. But it can be much better. We build upon decades of Structural Health Monitoring (SHM), structural risk and reliability research and development grown into a comprehensive research community and an important part of today’s infrastructure engineering. Our network incorporates a tremendous knowledge about SHM technologies, SHM data analysis, structural performance and deterioration as well as infrastructure operation. We want to enhance the benefit of SHM by novel utilization of applied decision analysis on how to assess the value of SHM – even before it is implemented. We know already that the value of SHM can be tremendous. We just have to quantify it. Knowing the value of SHM, we can improve the decision basis for design, operation and life-cycle integrity management of structures and facilitate more cost efficient, reliable and safe strategies for maintaining and developing the built environment to the benefit of society. Acting as the leader of the Innovation Committee of this COST Action, I am having promoting an event so-called Industry Innovation Days, which aims to establish and/or strengthen the communication along this supply chain, i.e. from the Academic/Manufacture levels to the Owner/Government levels. A showcase composed by real applications, with clear evidence of maturity degree (TRL 4 and/or above), supports this event in order to show the Value of SHM Information.

Long-term structural performance of pre-stressed concrete bridges: A risk-based monitoring

informed framework for life-cycle asset management

(2015-2017) Recently, the re-assessment of the collapse of the Koror-Babeldaob Bridge (in 1996), a pre-stressed bridge built by the cantilever method, concluded that this was due to excessive deflections that appeared and grew non-linearly some years after construction. Interestingly, similar trends have been found for a group of 56 similar bridge spans, raising the question whether such concerns could influence the maintenance and service life of a high number of pre-stressed bridges in Europe and beyond. Although individual material and structural factors have been researched, this problem can only be solved by integrating physical and probabilistic models and benefiting from the increasing use of monitoring data. In this context, this proposal aims to: Review existing models for shrinkage and creep at specimen level, Establish robust hybrid FE models for medium/long-term predictions, Develop a novel monitoring approach based on Digital Image Correlation (DIC), Formulate a time-dependent reliability assessment framework, addressing creep and shrinkage uncertainties, Produce representative performance-time profiles for pre-stressed bridges based on the proposed framework and models. The above will be demonstrated via a case study – the Lezíria Bridge – possessing a unique combination of factors: (i) available monitoring data, (ii) pre-existing analysis models and (iii) an intimate knowledge by Dr. Helder Sousa, the researcher, of its construction and behaviour. The findings will be directly relevant to the growing number of bridges with this problem, enhancing the European knowledge and competitiveness in the global infrastructure market. For this, an inter-disciplinary research and training programme has been set out, building on the researcher’s strong track record, expanding/honing his knowledge/skills, so that he can reach the forefront of highly qualified professionals able to solve problems in a creative/integrative manner and contribute to European expertise and wealth creation.

MAINLINE (FP7-TRANSPORT)

MAINtenance, renewaL and Improvement of rail transport iNfrastructure to reduce Economic and

environmental impacts

(2014) Growth in demand for rail transportation across Europe is predicted to continue. Much of this growth will have to be accommodated on existing lines that contain old infrastructure. This demand will increase both the rate of deterioration of these elderly assets and the need for shorter line closures for maintenance or renewal interventions. However, interventions on elderly infrastructure will also need to take account of the need for lower economic and environmental impacts. This means that new interventions will need to be developed. In addition tools will need to be developed to inform decision makers about the economic and environmental consequences of different intervention options being considered. MAINLINE proposed to address all these issues through a series of linked work packages that will target at least €300m per year savings across Europe with a reduced environmental footprint in terms of embodied carbon and other environmental benefits.

SmartEN (FP7-PEOPLE)

Smart Management for Sustainable Human Environment

(2013) Recently, a new generation of miniature wireless sensor platforms which utilize novel digital signal processing has emerged. These can be adopted to obtain large quantities of highly diverse sensor data that are continuously collected over a long period of time from multiple locations providing significant insight on the condition, demands and performance of the system. These developments open up a completely novel area of multidisciplinary research towards the ‘smart’ management of sustainable environment. Even though there are top research institutions working in the field of wireless sensors and others in the civil infrastructure reliability and management, most of the activity is fragmented and there is no significant activity in performing multidisciplinary structured research for developing integrated smart and dynamic systems for effective management of the built and natural environment. The aim of SmartEN is to fill this gap and push innovation through the development of an ITN network that will focus on the development and effective integration of emerging technologies targeting key application areas of current interest to the European Commission and internationally. Among 19 top ranked researchers, I have been involved as an Experienced Researcher. More info can be found here: http://www.smarten-itn.eu/researchers.html
