Crane load factors, a survival aproach

EN 1990 presents load factors for the building, whereas EN 1991-3 presents the load factors for crane - supporting structures. Within most industrial buildings, there is no clear separation of the crane supporting structure and the building. The paper presents an approach on how to determine the correct load factors for these type of buildings.The paper also focuses on how to cope with these factors, in case of retrofitting existing (Mill) buildings. Within the Netherlands, there is a special code for retrofitting of existing buildings (NEN8700), however, this code only specifies how to deal with factors presented within the EN1990. How to deal with EN1991-3 factors is explained within this paper.
