Abstract: Rehabilitation, upgrading, or strengthening of
structural members, especially columns, has become the
target of many researchers because columns are the most
important members in a building and the failure of columns
causes direct collapse in the building. This study
aims to get an assessment of the best pattern of steelframed
jacket used for strengthening axially loaded concrete
columns by numerically studying the behavior of the
column for different cases of the same amount of steel
jacket. The jacket consists of four angles and/or battens.
lacings, or battens with lacings. The nonlinear analysis
program designated as ARCC-SSJ (Analysis of Reinforced
Concrete Columns (Strengthened by Steel Jacket) is used
to compare different patterns with the same and different
cross-sections of battens and single lacing, as well as battens
and lacing with battens taken into account. It is found
that lacing with battens is the best pattern for the same
amount of steel jacket with different cross-sectional areas.
It is observed that the load-carrying capacity of the column
increased by approximately 1.8 and 1.15% over that of battens
alone in the case of a lacing angle of 60.832 ∘ and
74.407∘ with the vertical axis of the column, respectively.
