Este projecto visa um estudo de uma solução para uma ponte pedonal de Madeira Lamelada Colada (MLC) entre o Hospital Pedro Hispano e o Norte-Shopping, localizada na Senhor da Hora.
Inicialmente foram analisadas diversas variantes, com vários tipos de sistemas, sendo adoptada uma ponte formada por dois arcos, que se aproximam à medida que se afastam dos encontros unidos por contraventamentos em cruz. O tabuleiro encontra-se suspenso por tirantes e apoiados dos dois lados nos encontros.
Foi realizado uma pequena introdução histórica da utilização da madeira enquanto material de construção, a sua fabricação e os vários tipos de pontes pedonais em MLC. O uso da madeira em estruturas fez com que a abordagem do Eurocódigo 5 (EC5) tivesse uma maior importância.
A estrutura é modelada no programa de cálculo “DLUBAL ” através de um modelo de barras tridimensional de modo a efectuar uma análise estática e dinâmica global, recorrendo-se para tal a normas e princípios gerais de verificação de segurança dos regulamentos Europeus, nomeadamente os Eurocódigos das várias especialidades.
Apresentam-se em anexo vários desenhos da ponte, desenhos das peças de ligação, o mapa de trabalhos e quantidades, ideias preliminares, dimensionamento e a escolha dos ligadores e por fim os diagramas de esforços dos elementos aos Estados-limite Último.
The objective of this work is a study of a solution for a glued laminated (glulam) pedestrian bridge between the Pedro Hispano hospital and the Norte-Shopping, in Senhora da Hora, Matosinhos. Initially, several variants and types of structural systems were analysed. A bridge formed by two arches was selected, including cross bracing at the top. The deck is suspended by tension rods and simply supported on both sides. A small introduction was performed about the historical use of wood as a material for construction, their fabrication, and the different types of footbridges made of glued laminated timber. The use of timber in structures, made the Eurocode 5 (EC5) have a great importance as a topic. The structure was modelled with the program "Dlubal" based on a three-dimensional model of bars, so that a static and global dynamics analysis could be calculated, including verifications according to standards and principles of the European regulations, in particular the Eurocodes. Several bridge blueprints and detail drawings are presented in the Annex, along with a bill of quantities, preliminary ideas, dimensioning and selection of connectors and finally the force diagrams for the ultimate limit states.
