The performance of different nonlinear modelling strategies to simulate the response of RC columns subjected to axial load combined with cyclic biaxial horizontal loading is compared. The models studied are classified into two categories according to the nonlinearity distribution assumed in the elements: lumped-plasticity and distributed inelasticity. For this study, results of tests on 24 columns subjected to ...
The hysteretic behaviour of RC columns has been object of many experimental studies over the past years. However, the majority of these studies are focused on unidirectional loading. An experimental program was carried out where 24 columns were tested for different loading histories, under uniaxial and biaxial conditions. The experimental results are presented in this paper and are discussed in terms of global ...
The study of the seismic vulnerability of existent buildings in urban areas with moderated/high seismic risk is of extreme importance. Earthquake engineering experts, public authorities and general public alike agree on the idea that the assessment of the seismic safety and performance of the built environment is a matter of high priority. The proposed paper aims to carry out a structural fragility study where ...
Com o objectivo de caracterizar o comportamento de elementos estruturais parede-arco do Museu de Aveiro, foram realizados ensaios laboratoriais e in situ, com vista ao desenvolvimento e calibração de um modelo numérico. A partir desse modelo foi possível estudar o comportamento deste tipo de elementos quando solicitado por cargas cíclicas. Foi assim possível aprofundar o conhecimento sobre os materiais usados n...
Com vista a colmatar a escassez de informação acerca do comportamento e propriedades mecânicas das construções em alvenaria de adobe existentes na região de Aveiro, tem-se vindo a realizar várias campanhas experimentais. Procurando identificar aspectos tais como a rigidez, a capacidade resistente, a dissipação de energia e os mecanismos de colapso, essas campanhas têm incluído levantamentos dimensionais, estudo...
