Interactions between surrounding landscape biodiversity and intermittent rivers...

Landscape is a dynamic mosaic of various structures interacting together. Neglecting or overusing one part of this mosaic may boost up or damage the development of others. For instance, overgrazing may increase soil erosion process which may clog a river/stream. In this regard land use changes, climate change and landscape management may lead to increase the intermittency of the surface watercourses, as well as...

Using BIM to improve building energy efficiency: a scientometric and systematic...

The Architecture, Engineering, Construction, and Operations (AECO) sector is responsible for a great pro portion of the global energy consumption and associated environmental impacts. On this front, and from a sustainability improvement perspective, the use of Building Information Modelling (BIM) capabilities could represent an opportunity to improve these impacts in all steps of a building’s life. The main pur...

Numerical methods to predict human induced vibrations on low frequency stairs. ...

Nowadays, vibration serviceability criteria are becoming the governing factor in the design of most modern staircases, because their increasing susceptibility to human induced vibrations. Although more awareness have been raised to the dynamic design of new staircases, there are still few studies found in the literature that compare the different results of numerical methods for predicting vibrations with exper...

Utilização de ferramentas BIM na avaliação da eficiência energética dos edifíci...

Na última década as exigências relativas à eficiência energética dos edifícios aumentaram substancialmente. Por sua vez, as ferramentas BIM têm permitido a realização de tarefas de otimização de soluções na fase de conceção que antes eram muito trabalhosas, assim como difíceis de conciliar. Neste artigo faz-se uma revisão bibliográfica sobre a utilização de ferramentas BIM com a finalidade de obter edifícios en...

Direct integration methods versus modal superposition method, on predicting sta...

The majority of Finite Element software’s present two different solutions methods to perform time history analysis of the equations of motion due to dynamic (time-varying) loads: Direct Integration and Modal Superposition. This paper aims to assess which method should be employed in the design of modern flexible staircases, to more efficiently predict human induced vibrations. This was verified by estimating vi...

Plano para integração do BIM em diversas disciplinas do curso de engenharia civ...

Após a introdução do ensino de um software BIM (Autodesk Revit) na UC de Desenho Técnico Assistido por Computador do 1º ano do curso de Engenharia Civil, na Universidade da Madeira, em 2010, verificou-se que o nível de conhecimento BIM dos alunos se situa ao nível do modelador BIM e continua a ser insuficiente face às necessidades das indústrias AECO. Para uma formação mais sólida e completa na área do BIM, é i...

Dynamics of the land use changes and the associated barriers and opportunities ...

Considering the complex dynamics, patterns, and particularities that peripheral and insular territories/regions present—e.g., as the fragility, they show to achieve a sustain able development and growth—a study that analyzes the land uses of this territories is seen as pivotal to identify barriers and opportunities for a long-term sustained devel opment. Contextually, a general analysis was carried out through ...

Assessing land-use changes in european territories: a retrospective study from ...

The need to understand what land use is has motivated the development of programmes that aims to identify it and quantify it—CORINE Land Cover (CLC) in 1985. From this official and open geodatabase—through the using of geographic information system (GIS) tools—the amount of area established for each land use has been identified in all the 28 member states of the EU. This mostly corresponds to agricultural and f...
