摘要：The paper consists of a case study upon the possibility of adding a new floor to an existing building, with its primary focus being on the soil-structure interaction. The negative influence of differential settlements between individual foundations in addition to the supplementary load requires the analysis of the benefit when adding strip foundations into the initial foundation system. The research approach regards the position of the new strip foundations to be considered at three different elevations related to the height of the existing individual foundations. The soil-structure interaction is made in each case with different cross-sections for the strip foundations The analysis was performed according to the P100-3/2008 Romanian design code and Eurocode 7, using several finite element software. Based on the analysis outputs, conclusions and recommendations will be drawn upon the efficiency of this foundation retrofit solution as part of the building rehabilitation plan.
