Dans le cadre de calcul d’un pont rail, j’ai besoin de faire un calcul dynamique (par Pas de temps). Le modèle de charge «HSLM - A» utilisé pour ce calcul (selon EN1991-2, §6.4.6.1.1, tableau 6.4), composéde 10 rames élémentaires (selon EN1991-2, §6.4.6.1.1, figure 6.12 et tableau 6.3), est décrit ci-après:
merci de m’indiquer comment peut on faire ce type de calcul sur ROBOT.
Si possible d’avoir un exemple de fichier robot traitant ce type de problème.
Simple example of time history analysis modeling moving loads in contained in this forum post (message 2):
In your case you should also define a series of static cases corresponding to various positions of the train,
Then in time history you should define functions describing transition from one position to the next one - the loads in one position linearly descreasing while the loads in the next position linearly increasing (giving constant sum).
The number of various positions of the train results in different precision.
