- Alumni from the Polytechnic of Leiria: path & challengesPublication . Seco, Graça; Beato, Isabel; Duarte, ÂngelaIn this communication we will analyse the development of the Alumni Network of Polytechnic of Leiria, a higher public education institution in Portugal. The Alumni Network of Polytechnic of Leiria was constituted in February of 2012 with the aim to recover alumni relations, facilitating interactions, promoting the sharing of experiences and reinforcing the Institution’s recognition/image, empowering the long life learning, the information and knowledge updates and the reinforcement of an oriented community for the scientific and technological production. The Institution has around 12,000 current students and we estimate that 40,000 have finished their courses, short cycle’s, undergraduates and master’s degrees. The network has more than 4,000 registered alumni. In LinkedIn there are 13,500 former students connected and in Facebook there are more than 7,000 alumni following the page. This network develops activities towards former students such as: walk gatherings; anniversary cards; alumni days; the publishing of conferences, seminars, program offers; direct invitation to be a speaker; testimony collection; and alumni passport. The alumni passport is the official document sent to all alumni when they register that grants special conditions like access to canteens/bars and libraries; participation with special discount in events, conferences, courses and discounts in enterprises with an agreement with Polytechnic of Leiria. The testimony collection (flyers, videos) is also a great moment in the network since all the community can see the experiences before and after the alumni attended their school. The former students report their memories as resident students and the importance of the training received, presenting suggestions for the network life. Actually most of the activities are developed with the involvement and collaboration of current students who implement marketing strategies, creativity and new work tools to engage alumni. We regularly publish the initiatives/enterprises of our alumni and the prizes obtained. This is very courageous for them and we let all of the community know what they are doing, enabling them to be proud. This is also a way to inspire the current and future students. This is also a way to give visibility to the Institution which sees its reputation spread. Alumni of this initiative are also promotors of employment and are willing to recruit students from the same Institution. The mentors/ambassadors living in the country or even abroad are well engage to help other students. We are proud with the network development but conscious that a long way is waiting ahead, regarding the bigger involvement needed from the internal academic community if we want to reach volunteering and fundraise, another dimension of alumni relations and to proceed the alumni potential.
- Analysis Issues on Seismic Assessment of Existing StructuresPublication . Sousa, Romain; Biachi, Federica; Nascimbene, Roberto; Pinho, RuiMany existing RC structures worldwide were designed for gravity loads only, with inadequate lateral load resistance, lateral stiffness and poor detailing of the reinforcement. Moreover, the concept of regularity both in plan and elevation that characterise a good conceptual design was, in most cases, not taken into account. The introduction in Europe of the regulations for seismic assessment of existing structures imposed stricter performance requirements for building structures. In order to take into account the poor seismic behaviour of such buildings, recent seismic codes – namely EC8 and NTC08, introduce a number of prescriptions regarding issues such as analysis type, load distribution, accidental eccentricity, etc. At the same time, these codes give room for engineering judgment to be used with reference to the definition of structural and non-structural elements such as slabs or infill walls, and obviously leave it up to the analyst decisions regarding Finite Elements typology, meshing, mass modelling, etc. The main goal of this work is thus to provide an extensive and wide evaluation on the influence of each of the abovementioned parameter on the seismic assessment of structures. For this purpose, nonlinear static analysis, as well as nonlinear dynamic analysis are performed on a real building that has also been experimentally tested in the past. The results will hopefully provide indications on the relative importance of each modelling parameter or decision.

- Bibliotecas do Ensino Superior : inovar para envolverPublication . Correia, Dulce; Gonçalves, Liliana; Marcos, Rosa; Moreira, FranciscoAs Bibliotecas, nomeadamente as de ensino superior, têm que acompanhar as constantes mudanças tecnológicas, económicas e sociais que se vão operando no meio que as envolve, sobretudo ao nível do seu público-alvo, sob pena de morrerem lentamente. Uma Biblioteca que se encontra ao serviço de comunidades que lidam por natureza com a inovação e o empreendedorismo não pode alhear-se dessa realidade e tem que investir em novos procedimentos e novos serviços, adequados ao público-alvo que pretende atrair e envolver. As Bibliotecas do Instituto Politécnico de Leiria perseguem esse objetivo e, sempre que possível, apostam em procedimentos e novos serviços com o objetivo de envolver colaboradores e atrair o público que procuram servir. O Sistema de Identificação Digital utilizando a tecnologia RFID, a utilização do cartão do cidadão como cartão de leitor e a Estante Digital são exemplos disso. No âmbito do projeto de requalificação da Biblioteca Campus 3 (Escola Superior de Artes e Design da Caldas da Rainha do Instituto Politécnico de Leiria), financiado pelo QREN, foram adquiridos diversos equipamentos com a tecnologia RFID, com vista à implementação desta tecnologia quer na circulação e empréstimo, quer na inventariação das obras. Assim, este sistema efetua a inventariação automatizada das obras, permitindo saber com exatidão quantas estão desaparecidas ou arrumadas fora do lugar. Esta tecnologia, integrada com o software de gestão de bibliotecas, permite ainda emprestar e devolver vários itens em simultâneo em vez de os passar individualmente pelo leitor ótico, procedendo também em simultâneo à desativação das etiquetas no empréstimo e à ativação na devolução. Outra inovação instituída por estes serviços foi a utilização do Cartão de Cidadão, enquanto cartão de leitor. Com o apoio dos técnicos dos Serviços de Informática, foi desenvolvida uma aplicação para que o Cartão do Cidadão passasse a ser usado como cartão de leitor das Bibliotecas do IPLeiria, permitindo, desta forma, tornar as atividades de circulação e empréstimo mais ágeis e rápidas. Por outro lado, uma vez que estes serviços deixaram de emitir cartões de leitor, este processo veio também permitir uma redução de custos. Para além das tecnologias atrás referidas, que permitiram uma agilização dos movimentos nos balcões de atendimento, foi também introduzida outra inovação na área da divulgação e promoção do fundo documental: a Estante Digital. Este novo serviço pretende ir ao encontro dos novos nativos digitais, que querem a informação à distância de um clique. Assim, às estantes convencionais juntam-se agora estantes digitais, com códigos QR que os conduzem, através dos dispositivos móveis, a conteúdos digitais dos mais variados temas e áreas.
- Blind Prediction of a Full-Scale RC Bridge Column Tested Under Dynamic ConditionsPublication . Bianchi, Federica; Sousa, Romain; Pinho, RuiThe definition of appropriate modelling approaches combined with a consistent software framework is a topic of major importance in the present days for structural engineering in general and, particularly, for earthquake engineering. The accuracy of the results obtained in the recent “Concrete Column Blind Prediction Contest 2010” for a full-scale reinforced concrete bridge column tested on the NEES Large High-Performance Outdoor Shake Table, seems to indicate that current modelling strategies are on the right track. The 1.2 m diameter cantilevered column spans 7.2 m from the footing. A massive 230 tonne reinforced concrete block supported by the column generates the inertial forces to mobilize the column capacity. Seismic performance was investigated under 6 ground motions, starting with lowintensity shaking and bringing the column progressively to near-collapse conditions. Based on the obtained results from the pre-contest simulation, as well with the post-contest analysis, it was possible to extract some important conclusions regarding the application of several strategies, namely the use of different type elements, element discretization, constitutive laws for materials.
- Blind Prediction Tests as a Benchmark to Improve the Seismic Response of Fibre ModelsPublication . Sousa, Romain; Correia, António A.; Almeida, João P.; Pinho, RuiThe seismic behaviour of reinforced concrete framed structures involves a number of nonlinear material and geometrical phenomena that are impossible to model exhaustively in a single model. Furthermore, past studies showed that the most correct modelling options from the scientific viewpoint are sometimes challenged by experimental results. Over the years, attempts have been made to identify and measure the importance of different modelling options. This work intends to consolidate some of these findings and further extend them in order to progressively bridge the gap between solidly established theoretical principles and shaking table test results. The response of three different structures used in international blind prediction test challenges serves as benchmark to assess the goodness-of-fit of alternative numerical solutions. The interpretation of the results highlights the sensitivity of the response with respect to the modelling choices and provides indications towards the development of optimized numerical analyses.
- Development of study and communication competences in the transition to higher educationPublication . Seco, Graça Maria dos Santos Batista; Filipe, Luís Pereira; Pereira, Patrícia; Alves, SandraResearch has been stressing the importance and relevance of intra and interpersonal competence development in the promotion of the student academic success and general wellbeing. In the transition to Higher Education, the individual is confronted with different challenges and changes to which he must try to answer in a correct way so as to reach a positive and satisfactory adaptation. Separation from family and friends, the adaptation to new tasks, new personal, social and academic demands are considered inherent difficulties to this process of transition. As far as the academic dimension is concerned one of the most relevant difficulties is related to the adequacy of study strategies, used in secondary education, to the demands of the new context. The recent course changes concerning the Bologna Process demand the student the need to develop an active and more self-controlled learning process. The consciousness of the importance that the student should become a real manager of his study and communicational competences, led the Student Support Service of the Polytechnic Institute of Leiria (SSS/PIL) to implement two training programmes focused on the following transverse competences: Communication and Emotional Intelligence and Study Methods and Time Management, with the duration of 9 hours each. Those programmes, supervised on active methodologies, had, as their main objective, not only the development of adequate strategies in communication and interpersonal relationship, but also the achievement of strategies that contribute to improve the academic work and performance, stressing, thus, the importance of self-regulation to the success of the PIL student. In this context, with this paper proposal, we want to show the structure and implementation as well the main results of the two training programmes developed by SSS, in the 4 campus of PIL, in which 126 students were involved. In general, the programmes were assessed, very satisfactorily, by students who highlighted the importance of this type of training, especially in the context of the changes that took place, in Higher Education, due to the Bologna Process.
- Effect of Different Modelling Assumptions on the Seismic Response of RC StructuresPublication . Sousa, Romain; Eroglu, T; Kazantzidou, D.; Kohrangi, M.; Sousa, Luís; Nascimbene, Roberto; Pinho, RuiThe introduction of new regulations for seismic assessment of structures established stricter performance requirements for existing buildings. In order to account for the poor seismic behaviour of such buildings, recent seismic codes, namely Eurocode 8 (EC8), introduce a number of prescriptions regarding issues such as analysis type, load distribution, accidental eccentricity, etc. At the same time, these codes give room for engineering judgment to be used with reference to the definition of structural and non-structural elements such as slabs or infill walls, and obviously leave the modelling assumptions, such as Finite Elements typology, meshing, mass modelling, etc. to the analyst decision. As such, four existing RC buildings, representative of traditional Mediterranean construction, considering different modelling assumptions, were subjected to an extensive number of nonlinear static analyses. The interpretation of possible deviations in the results will hopefully provide indications on the relative importance of each modelling parameter or decision.
- Escala de competências de estudo: resultados de um estudo de validação no Instituto Politécnico de LeiriaPublication . Seco, Graça Maria dos Santos Batista; Almeida, Leandro S.; Alves, Sandra; Pereira, Patrícia; Filipe, Luís PereiraDescreve-se um estudo exploratório de construção e validação de uma escala voltada para a avaliação das competências de estudo e abordagens à aprendizagem por parte de alunos do Ensino Superior Politécnico. Uma amostra de 264 alunos foi considerada neste estudo, tendo-se recorrido à Escala de Competências de Estudo (ECE – Almeida & Joly, em preparação). Os resultados, longe de confirmarem as dimensões iniciais propostas pelos autores, parecem identificar duas formas de auto-regulação nos alunos: uma mais centrada nos comportamentos e condutas quotidianas (organização do estudo) e outra mais dirigida por aspectos motivacionais e cognitivos. São apresentados os resultados centrados na delimitação das duas dimensões, assim como a sua associação a níveis de rendimento escolar (disciplinas em atraso e médias obtidas) e diferenciação segundo o género, idade e tipo de curso frequentado pelos alunos. As correlações com o rendimento são mais elevadas tomando a dimensão mais comportamental da autoregulação, sendo que as alunas apresentam médias mais elevadas nas duas dimensões e os alunos mais velhos apresentam níveis mais elevados de auto-regulação em termos motivacionais e cognitivos.
- Evaluation of Analytical Methodologies to Derive Vulnerability FunctionsPublication . Silva, Vitor; Varum, Humberto; Crowley, Helen; Sousa, Romain; Pinho, RuiThe recognition of fragility functions as a fundamental tool in seismic risk assessment has led to the development of more and more complex and elaborate procedures for their computation. Although vulnerability functions have been traditionally produced using observed damage and loss data, more recent studies propose the employment of analytical methodologies as a way to overcome the frequent lack of post-earthquake data. The variation of the structural modelling approaches on the estimation of building capacity has been the target of many studies in the past, however, its influence in the resulting vulnerability model, impact in loss estimations or propagation of the uncertainty to the seismic risk calculations has so far been the object of restricted scrutiny. Hence, in this paper, an extensive study of static and dynamic procedures for estimating the nonlinear response of buildings has been carried out in order to evaluate the impact of the chosen methodology on the resulting vulnerability and risk outputs. Moreover, the computational effort and numerical stability provided by each approach were evaluated and conclusions were obtained regarding which one offers the optimal balance between accuracy and complexity.
