Original Abstract

Strengthening of steel columns means increasing of cross-sectional area, which can be achieved by welded plates. Strengthening is often considered for historical buildings with steel which is no longer produced. The strength of welded plates must therefore vary from the strength of the base column. The most feasible is strengthening under load, i.e. welding without unloading the structure, at least from self-weight. The behavior of columns with cross-section HEA 100 strengthened by various steel grades under load is investigated by finite element analysis in ANSYS software using shell elements. The results show that using higher steel grade for welded plates than that of a base column is useful only for columns with low slenderness. Columns HEA 100 with relative slenderness about 1.4 are affected the most by the preload, i.e. the load under which the column was strengthened. The decrease in load resistance is also more significant for columns strengthened using plates of higher steel grade.
