- Análise do comportamento de vigas de betão armado reforçadas à flexão simples com CFRPPublication . Neto, Pedro; Alfaiate, J.; Vinagre, JoãoO reforço de estruturas de betão armado com recurso a CFRP é actualmente uma prática corrente. Este artigo tem como objectivo ilustrar a aplicação de um modelo numérico ao caso de uma viga simplesmente apoiada com quatro pontos de carga. Pretende-se aferir da importância dos modos de rotura locais provenientes de tensões de corte ao nível da interface, no comportamento à rotura de um elemento à flexão simples.

- The influence of the mode II fracture energy on the behaviour of composite plate reinforced concretePublication . Neto, Pedro; Alfaiate, J.; Almeida, J. R.; Pires, E. B.; Vinagre, JoãoIn this paper, the finite element method is used to analyse the behaviour of concrete externally strengthened by sheets of carbon fibre reinforced polymer (CFRP). The bond between concrete and CFRP is modelled by a discrete approach using interface elements. The mechanisms involved in the behaviour of externally reinforced concrete specimens are complex, the global strength of the specimen being governed by the strength of each individual material as well as by the adhesion properties conferred by the epoxy. It is observed in experiments that, in most cases, failure occurs due to the loss of cohesion of a portion or lamina of concrete attached to the epoxy-fibres layers, the latter remaining intact. In this paper, the results of numerical simulations of bond tests are presented, aiming to contribute for a better understanding, in qualitative and quantitative terms, of mode II fracture energy in concrete and its influence on the behaviour of the interface concrete-FRP.

- ITs in engineering education: joining efforts between SPEE and IGIPPublication . Williams, Bill; Neto, Pedro; Cardoso, Alberto; Carvalho, Carlos Vaz de; Magalhães, Fernão de; Rasteiro, M. Graça; Restivo, Maria Teresa; Zutin, Danilo G.The International Society for Engineering Education (IGIP) and The Portuguese Society for Engineering Education (SPEE), the first being the oldest European Society for Engineering Education in Europe and the second the very young Society for Engineering Education in Portugal, have been intensifying the collaboration between the two societies as well as the exchange and dissemination of information about their relevant activities, whilst promoting understanding and cooperation between their respective members. One possible way is to create joint working groups, open to the members of both societies, on common topics of interest. In fact, both societies already kicked off this activity. The first initiative happened during the 1st World Engineering Education Flash Week (WEE), Lisbon, 2011. The SPEE-IGIP Flash Moment was a one day event integrated in the main Conference, which was dedicated to “Information & Communication Technologies in Engineering Education”. ITs allow the development of different teaching strategies which contribute to enhance the learning outcomes of students. ITs are also particularly suited to develop Life Long Learning tools, in a broad range of Engineering subjects, either open to the general market or oriented to a very specific public. Examples of teaching strategies involving ITs have been addressed during the Flash Moment SPEE-IGIP which took place during WEE, and some are described in detail in the present work.
- Keeping them involved: encouraging and monitoring student activityPublication . Williams, Bill; Neto, Pedro; Carvalho, IsabelIn the teaching of engineering, lecture classes are often essentially expository with students in a passive role, not preparing learners for autonomous work and this may contribute to high failure and attrition rates. One way to combat this is through the application of Active Learning (AL) methodologies. In this paper results are presented from the application of an AL Methodology in the classroom and outside it for a last year subject of a BEng degree. A Learner Activity Monitoring Matrix has been used to monitoring in-class learner activity. Also described is the implementation of AL outside class using an online learner management system (LMS) which permits voting by students on the quality of solutions proposed by their peers to resolve engineering problems posed by the lecturer. Empirical data regarding the online participation in the process of each learner is provided. A pre-post survey to reveal student perceptions regarding these methodologies is also presented.

- Modelação da aderência entre o betão e materiais de reforçoPublication . Neto, Pedro; Vinagre, João; Alfaiate, J.O sucesso do reforço de estruturas de betão armado, com recurso à técnica de colagem de materiais compósitos, está intimamente relacionado com o comportamento da ligação entre o betão e o FRP. A correcta quantificação da aderência entre estes materiais é pois, um aspecto que tem vindo a merecer atenção crescente, apresentando-se resumidamente neste artigo, os principais modelos matemáticos para a modelação da ligação por aderência.
