J.; Roque, D.; Veiga, M. R.; Lopes dos Santos, A. R.; Correia, M. J. M. Grantham, J. Custodio and S. Real This article discusses and presents the methods and results of the digital survey carried out, in 2025, of Paimogo Fort, a military structure built in 1674 in the municipality of Lourinhã. The digital survey aims to safeguard and monitor the conservation state of this classified coastal heritage site. Paimogo Fort underwent a conservation intervention in 2024 to preserve and strengthen the values of its individual and collective memory, transforming it into a meeting point for the memories of local communities and as a source for recovering and bringing awareness of traditional knowledge within the region. 2025-06-01T00:00:00Z http://repositorio.lnec.pt:8080/jspui/handle/123456789/1018079 Durability of pultruded GFRP laminates under accelerated laboratory and natural environmental ageing conditions Hassanshahi, O.; J.

R.; Cabral-Fonseca, S.; Garrido, M. This paper presents an experimental study about the synergistic effects between different exposure environments, likely to be found in civil engineering applications, and sustained flexural loading on the durability of pultruded glass fibre reinforced polymer (GFRP) profiles. Two off-theshelf GFRP profiles, comprising E-glass fibres and vinyl ester or unsaturated polyester resins, were subjected to sustained bending at service load levels corresponding to 10% and 20% of their flexural capacity; simultaneously, the profiles were exposed to the following three ageing environments, for periods of up to two years: (i) outdoor environmental exposure in a mild Mediterranean climate; (ii) hygrothermal exposure by continuous condensation at 20 (±2) ◦C, and (iii) indoor controlled environment at 23 (±2) ◦C and 50 (±10)% relative humidity. The environmental exposure caused reductions in the flexural strength of unloaded specimens of 4%–15%, which were higher in case of hygrothermal exposure. The sustained service loads acting synergistically with the different ageing environments caused negligible additional degradation of the flexural strength of both types of profiles. These results, together with the data available in the literature, indicate that for the service load levels found in civil engineering applications, durability studies can be carried out without considering the synergistic effects of sustained loading, significantly reducing their complexity. 2024-02-01T00:00:00Z
