Girder-pier connection modeling according to Eurocode 3

Razmatra se modeliranje priključaka između nosača i stupova uvažavajući njihovo stvarno ponašanje opisano Mj-f krivuljom. Prvo su općenita razmatranja o novoj filozofiji proračuna priključaka, prema Eurokodu 3. Zatim se opisuje metoda komponenata kao analitička metoda karakterizacije priključaka. Identificirane su i obrađene komponente koje čine priključak nosača i stupa u vijčanoj izvedbi. Primjena opisanog modeliranja pokazana je posebno razvijenim kompjutorskim programom CoP.The modeling of girder/pier connections is analyzed taking into account real behavior of such connections as described by the Mj-f curve. General considerations relating to the new connection design philosophy, as based on Eurocode 3, are given in the initial part of the paper. The method of components, an analytical method for characterization of connections, is then described. Components enabling bolted connection between girders and piers are identified and analyzed. The use of the described modeling procedure is shown by means of a specially devised computer program CoP
