Structural robustness of steel framed buildings subjected to accidental actions

The approach of Eurocode 1 to accidental actions was briefly presented in the paper. These specific actions occur very rarely but due to their high intensity may result in the total collapse of  the building. Together with the description of structural robustness requirements, accidental design situations were discussed in accordance with the Standard PN-EN 1991-1-7. Furthermore, the analysis of steel framed building was carried out. The analysis concerns removal of a column on the lowest storey and was executed with the use of Autodesk Robot Structural Analysis Professional 2013.
