Os perfis tubulares de aço de secção elipsoidal ou semi-elipsoidal fornecem novas soluções com bastantes potencialidades estéticas e características estruturais interessantes. Contudo, existe ainda pouca informação disponível ...

Bridge falsework systems, in particular those constituted by proprietary modular framed systems of metallic elements connected by special couplers are frequently used in structural engineering works. The popular Cuplok® ...

Bridge falsework systems are frequently used during the construction, rehabilitation and retrofit works of bridge structures. These structures have a significant impact on the cost, construction rate and construction ...

Survey of existing timber structures often includes the need to allocate mechanical properties to structural timber members. This task has to take into account the huge variability of timber's properties (within and between ...

One major difficulty one has to face in the assessment of old timber structures concerns the assessment of the effective strength of timber cross sections with biological damage. Its effects may generally be considered, ...

Bridge falsework systems are frequently used in the construction, rehabilitation and retrofit works of bridge structures. These structures have a significant impact on the cost, construction rate and construction safety of ...

This paper concerns the design of bridge construction equipment (BCE). First an extensive design review of existing standards and codes of practice published in the USA and Europe is presented. A comparison is given ...

A parafina tem sido utilizada ao longo dos tempos como proteção superficial da madeira. A sua utilização por impregnação para melhorar a resistência à biodegradação é recente. Pretendeu-se com este estudo determinar a ...

The fire performance of timber structures is largely influenced by the behaviour of the connections. Current structural fire design rules for timber connections, according to EN 1995-1-2 [1], are based on a limited number ...

Ensaios de fogo preliminares realizados em ligações tradicionais de madeira foram comparados com os métodos simplificados e avançado propostos no Eurocódigo 5, observando-se uma boa concordância entre os modelos de cálculo ...
