Accurate prediction of concrete creep and shrinkage remains challenging owing to the significant variability of influencing parameters, particularly environmental factors such as temperature, relative humidity, and rainfall. ...

This paper presents the implementation of a Structural Health Monitoring system on the Mosteirô Bridge, designed by Professor Edgar Cardoso and built in 1973. The monitoring system aims to support the digital transition ...

Transverse stiffeners provide lateral support to slender webs along their span, enhancing the shear buckling resistance of steel plate girders. Moreover, intermediate transverse stiffeners are particularly crucial, because ...

This paper addresses the buckling resistance of transversally stiffened steel plate girders subjected to combined axial force, bending moment, and shear. A total of 6 000 GMNIA finite element simulations were performed and ...

Climate change poses increasing challenges to infrastructure, particularly bridges, requiring advanced adaptation and monitoring strategies. However, the lack of long-term monitoring data challenges the effective ...

The construction industry increasingly uses prefabrication for the significant advantages in cost-effectiveness, production speed, and environmental sustainability. Achieving high-quality building outcomes demands rigorous ...

Vibration-based methods for damage detection have been widely used, particularly those relying on ambient excitations. These methods are based on the principle that changes in a structure's physical properties, such as ...

Apresenta-se a atualização e o melhoramento da modelação dos efeitos das expansões do betão num pilar da ponte da Foz do rio Dão, integrada no IP3, sobre a albufeira da barragem da Aguieira, ponte que foi substituída em ...

Com o avanço tecnológico, a monitorização estrutural passou a utilizar uma variedade significativa de sensores, resultando num grande volume de dados coletados em tempo real, o que exige um tratamento adequado para a ...

A observação do comportamento estrutural da ponte sobre or io Angueira iniciou-se durante a construçºão com a instalação de equipamento no interior do betão. Antecedendo a entrada em serviço da ponte, foram realizados ...
