Concrete gravity dams are mass concrete structures, often built on rock mass foundations, conceived to rely upon their weight for stability. To prevent sliding, these structures are usually keyed/embedded into the foundation, ...

Stability analyses of geotechnical structures in rock are traditionally performed using deterministic methods. In Europe, Eurocode7, introduced in the beginning of the 21st century, adopts limit state design and ...

Apresentam-se os resultados do estudo, em modelo numérico, do comportamento sísmico da barragem da Chicamba, em Moçambique. Foram realizados cálculos em regime elástico e cálculos não lineares tendo em consideração o ...

Neste trabalho apresenta-se um modelo tridimensional de elementos discretos para análise do comportamento dinâmico da barragem do Cabril tendo em conta o efeito das juntas de contracção. Os resultados são comparados com ...

As barragens de Ferradosa e Olgas, localizadas no Alto Douro, nos concelhos de Freixo de Espada à Cinta e Moncorvo, respetivamente, foram construídas entre 2007 e 2009. São estruturas gravidade de betão com cerca de 30 m ...

A determinação da resposta dinâmica das obras e o acompanhamento da evolução do seu comportamento durante as várias fases da vida é muito importante, estando inserido nas atividades do controle de segurança estrutural. A ...

The Foz Tua hydroelectric development is located in the north of Portugal at the mouth of the Tua river, a tributary of the Douro river, and is equipped with 270 MW of power capacity, making it a very important asset in ...

Civil engineering structures are generally supposed to have long operation life spans during which they are submitted to many factors, both environmentally and human-induced, that degrade their condition and performance, gradually ...

The safety of concrete arch dams depends to a large extent on the soundness of the foundation rock mass. The large arch dams presently under design and construction apply very significant loads to their abutments and ...

Earthquake damage in historic masonry buildings is generally caused by the collapse of individual portions that become detached form the structure and fail by overturning. These mechanisms are mainly governed by the discrete ...
