Purpose: this degree project will examine the possibilities of increasing the structural integrity in case of fire of a preexisting concrete building according to the rules in EKS 11, specifically for a hospital building. Furthermore, the degree project will provide solutions to increase the structural integrity in case of fire. Method: the study is based on a technical report provided by Kadesjös Ingenjörsbyrå AB where information about the hospital buildings technical aspects is presented. To examine current rules for fire-resistance rating of the hospital building, the regulations presented in BBR and EKS 11 were studied. Products had to fulfill the criteria of the European testing standards when they were evaluated as solutions that would increase the structural integrity of the building. The products were then evaluated according to the criteria presented in Eurocode 2 when dimensioning with tabulated data. An interview were held with Michael Försth professor in structural and fire engineering. Professor Försth were asked questions to evaluate potential methods and products that could increase the fire-resistance rating of the hospital building. Results: showed that proposed solutions are able to increase the structural integrity in case of fire of the hospital building to a degree where they were able to fulfill the requirements. Not all solutions were appliable on all building components of the hospital buildings. The difference in technical aspects of the solutions were presented. Conclusions: the identified solutions for increasing the structural integrity in case of fire are rock wool insulation, fire protection paint, additional concrete casting on columns and installation of sprinkler system. The solutions differ in technical aspects such as the space they take when implemented, weight increase when implemented, the amount they increase the structural integrity in case of fire when implemented and the method of implementing the solutions.
