C. da; Oliveira Santos, L.; Campos Costa, A.; Coelho, E.; Bairrão, R.Este relatório apresenta a estratégia de I&D&I adotada pela Comissão Científica Departamental (CCD) do Departamento de Estruturas do LNEC (DE), em coerência com a estratégia de investigação e inovação (E2I) estabelecida pelo LNEC para o período 2013-2020 e respondendo ao Plano de Ação da E2I sobre o aprofundamento da E2I nas unidades departamentais do LNEC. Esta estratégia do DE enquadra nove linhas prioritária...
Robustness and risk evaluation of bridge falsework structures
André, J.; Beale, R.; Baptista, A. M.Bridge falsework systems are one of the most common temporary structures used in the construction industry, namely to support the formwork during the construction, rehabilitation or retrofit works of concrete bridges and viaducts. A key contribution of this paper is to propose a novel risk management methodology based on newly developed robustness and fragility indices. Advanced stochastic investigations are ca...
Numerical investigation of bridge falsework structures
André, J.; Beale, R.; Baptista, A. M.Bridge falsework systems are one of the most common temporary structures used in the construction industry, namely to support the formwork during the construction, rehabilitation or retrofit works of concrete bridges and viaducts. In this paper the results of numerical studies of a selected structural system are presented using a novel joint finite element and information gathered from the experimental tests. T...
Experimental behaviour of bridge falsework joints
André, J.; Beale, R.; Baptista, A. M.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® system was chosen for this study. A total of 192 tests were carried out divided in four types of joints. For each type of joint, several pa-rameters, critical to define the joints’ behaviour, we...
Recent advances and existing challenges in the design of bridge falsework systems
André, J.; Beale, R.; Baptista, A. M.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 the supported permanent structures. However, the relevant stakeholders often do not consider them as important as permanent structures, and in recent years, a high number of accidents involvi...
Bridge Construction Equipment: An Overview of the Existing Design Guidance
André, J.; Beale, R.; Baptista, A. M.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 concerning the design principles used, the design rules specified concerning structural analysis, types of loads, load combinations and safety factors. Additionally, discussion is presented about de...
