Dimensionamento estrutural de ponte-cais de madeira para Reserva Nacional de Marromeu

Abstract

The present professional internship report comes within the scope of the work of the culmination of the course to obtain a degree in Civil Engineering, where a professional internship at Nyeleti Engenharia, Lda with a duration of 4 months. will be aspects related to the structural design of a pier bridge that will be implanted on the banks of the Micelo River, inside the Marromeu National Reserve (RNM). The pier will be made of wood and dimensioned to resist the actions of pedestrian traffic, horizontal actions (wind and water) and low magnitude seismic action. The same it will serve for the crossing and handling of loads (goods) of the inhabitants of the reserve. The structural elements of the bridge will be connected by means of nut bolts. Using wood in order to take into account the integration of the landscape as it is an area of conservation, the availability of material that has an impact on cost reduction, as well as as well as the technical constraints that affect its execution. The structure was modeled in the calculation program “DLUBAL RFEM 5.25” through a three-dimensional bar model in order to carry out a global static analysis, using general rules and principles of safety verification of regulations Europeans, Eurocode 5 (EC5). The dimensioning consisted of verifying the States Ultimate Limits (traction, compression and bending), Service Limit States (deformation) and Fire resistance (TRADUÇÃO NOSSA).
