Limit stiffness in soil structure interaction of buildings

A model of the behavior of column load in framed building is used to analyse parametrically the growth of the soil-structure stiffness as a function of the construction sequence The model was also tested using settlement readings of one multi-story building The results show that this stiffness does not grow continuously but there is a limit stiffness after which the interaction is completed Un modele du comportement des charges dans les colonnes des batiments est utilize pour annaliser le augmente de la rigidite sol-structure dans la construction Le modele a ete teste avec les lectures de tassement d’un ouvrage de plusieurs etages Les resultats montrent que la ngidite n’augmente pas de maniere continue mais qu’il y a une ngidite limite apres l’aquele 1’interaction est termmee
