Ao longo dos anos recentes, a atividade desenvolvida nas áreas de engenharia tem-se apoiado cada vez mais na utilização de ferramentas de software apropriadas. Estas ferramentas são muitas vezes desenvolvidas especificamente para dar resposta a um problema muito bem definido, faltando-lhes a capacidade para resolver de forma eficiente problemas semelhantes computacionalmente mais exigentes. A paralelização destas ferramentas é uma das abordagens existentes para permitir aumentar a sua eficiência e aumentar a complexidade dos problemas admissíveis. Este relatório introduz o programa ParFludan, um programa paralelo para análise estrutural pelo método dos elementos finitos, que surgiu da necessidade de melhorar o desempenho do programa Fludan-RAS. Executado no cluster Medusa do LNEC, este novo programa permite tratar problemas de maior complexidade do que o original, com melhorias significativas ao nível dos tempos de execução. Além da descrição do processo de paralelização do programa original e das tecnologias para tal utilizadas, é também feita a análise do programa desenvolvido e são dadas instruções para a sua utilização, com o objetivo não só de facilitar a utilização do ParFludan como também deprovidenciar algumas linhas de orientação para a paralelização de outros programas em condições semelhantes.

This document presents the developments in the first 18 months of activity of LNEC in PIANO project (Policies, Innovation, and Network for Enhancing Opportunities for China-Europe Water Cooperation) financed by the European Union (Horizon 2020) and the Chinese Secretariat of China Water Platform Europe (China-Europe Water Platform, CEWP, http://cewp.org/), as key lessons learned from the Portuguese participation, led by Laboratório Nacional de Engenharia Civil (LNEC). PIANO project aims to strengthen cooperation in the field of water between Europe and China, promoting the creation of networks of enterprises (including SMEs), entrepreneurs, NGOs, policy makers, regulators and funding agencies to create social opportunities and business. The PIANO project objectives are (1) strengthening and expanding the existing network of the China Europe Water Platform (CEWP) to cover all relevant actors for water research and innovation relevant for China Europe water cooperation; (2) identification of European technological water innovations and areas for joint development of technological solutions that have a potential for implementation in China; (3)identification of drivers and barriers and elaborating strategies for overcoming such barriers and taking advantage of drivers for implementation and replication of technological water innovations; (4) promotion of knowledge exchange and policy dialogue to build an enabling environment for the uptake of technological water innovations with a great potential for implementation, further replication and market uptake in China; (5) consolidation of a shared strategic research and innovation agenda between Europe and China in the water domain; and, (6) effective dissemination and mainstreaming of the project results within China, Europe and worldwide to various target audiences. The priority research areas focus on societal challenges related to Agricultural water management (WP2_1.a), to Municipal water management (WP2_1.b), to Industrial water management (WP2_1.c), to river basin management highlighting the problem of floods (WP2_1.d) and to the Water for energy nexus (WP2_1.e). The project consortium is composed of nine partners of which eight are located in eight different EU Member States and one is based in China. The consortium encompasses partners from high level academic institutions and experienced research institutes to non for profit organizations, from European umbrella associations to a commercial SME and a large international company. The PIANO partners are supported in their activities by many Chinese institutes and research centres. LNEC leads the development of tasks (WP2_1d) and (WP2_1.e). In the case of the task "Water for Energy" LNEC has the support of EDP / Labelec. Within the activities led by LNEC an inventory of about 50 technological water innovative solutions (TWI) was developed in the thematic areas WP2_1.d and WP2_1.e. Later, following several prioritization criteria, 20 TWIs of each of both thematic areas were ranked in descending order of suitability and potential deployment opportunities in China. They are presented for discussion.

The construction and operation of dams, associated with the use of water resources, aim generically at the energy producing, water supplying and, in some cases, flow regulating and flood controlling. Considering the dam dimensions and the potential risks associated with its collapse, due to the occupation of the downstream valley, and to the costs of the construction, maintenance and rehabilitation, the use of probabilistic principles in its design, as it is already performed for other type of structures, is justified. With this thesis work plan, it is intended to establish a methodology for the structural safety analysis of concrete dams based on the definition of safety evaluation criteria, considering the partial safety factors obtained through structural reliability analysis. For that purpose, the uncertainties involved in the safety of concrete dams shall be statistically quantified, through the definition of probabilistic distributions for loads and material properties, using, in addition to the elements found in the literature, the information available at LNEC about those features, resulting from the monitoring of the concrete dam behavior during the construction, first filling and operation periods. Later, the partial safety factors shall be calibrated analysing the outcomes of the structural reliability analysis performed to models of concrete dams, representative of the standard solutions for different design situations. It is expected that this work contributes to the discussion on the design criteria of concrete dams and can be integrated into future revisions of the Portuguese dam safety regulation.

This report is a deliverable of USE-iT (Users, Safety, Security and Energy in Transport Infrastructure); a Horizon 2020 Coordination and Support Action (CSA) project managed by the Forum of European Highway Research Laboratories (FEHRL). The aim of USE-iT is to better understand the common challenges facing transport modes and in conjunction with stakeholders to produce a multi-modal research roadmap to develop technologies and approaches to addressing these challenges. In addition to a work package on management (WP1) and on dissemination activities (WP5), USE-iT is divided into three technical Work Packages addressing important challenges facing all modes: providing better customer information (WP2); improving safety and security (WP3) and reducing carbon emissions and energy consumption (WP4). This report relates to Work Package 4 (Deliverable D4.2) on reducing the carbon emissions and energy consumption associated with the transport sector. In the first WP4 report [D4.1], a significant number of technologies, materials and approaches were identified which could help reduce transport energy consumption and reduce carbon emissions. In the present report [D4.2], the common challenges facing all modes as they work to reduce transport carbon emissions are identified, and the potential areas of cross-modal research that could help to address these challenges are evaluated and prioritised.
