Strengthening of Edge and Corner Columns using Concrete Jackets

Strengthening of columns using concrete jackets depends on friction at the interface between them. So strengthening edge and corner in only one story needs a large cross section area due to shortage length which leads architectural issues. This research aims study Jacket more than increases original column. As result, load transferred from column jacket will be increased. Thirteen models were done ANSYS program effect various factors capacity such as number strengthened floors, type (two sides or three sides), whether there shear connectors not. The results showed that case columns, it is preferable strengthen by making least two floors increase surface area, thus an acceptable percentage. compared with Indian code IS 15988 (2013) shown differently because equations depend presence full bond Jacket, does not occur, but rather Doi: 10.28991/cej-2021-03091716 Full Text: PDF
