The basis of this thesis was that Kåver & Mellin Uppsala wanted todetermine if they should train their employees in the software RobotStructural Analysis. The company had licenses for the program that theydid not use due to lack of experience. The purpose of the project wastherefore to examine how Robot is used for designing structures and tocompare its usefulness to its competitor FEM-Design. The comparison ofusefulness was made by designing an identical structure in bothprograms. The focus of the study was to compare three main areas,workflow, areas of use and calculation results. This was made for themost common construction elements that were limited to concrete slabs,concrete walls, steel columns and steel beams.The study proved the programs to be similar. Designing steel profilesis more efficient in Robot. Another advantage of Robot is that there isan official online help page and a useful online forum, that FEM-Designlacks. One significant disadvantage of Robot is that the calculationsfor concrete are made with outdated national standards for Eurocode.The disadvantage was crucial and led to the conclusion that Kåver &Mellin Uppsala should wait for updated standards before using theprogram fully but they could start using Robot for load calculationsand steel design.
