A structural system consists of different members such as Footing, column, beam, slab etc. Column are basically vertical members which goes throughout the height of the structural system i.e. from foundation to Terrace.
Column can be categorized on different basis depending on its cross section, length, behavior, bracing, longitudinal reinforcement etc.

The difference between Braced Column and Unbraced Column are as follows:
|A column may be considered braced in a given plan if lateral stability of the structure as a whole is provided by walls or bracing.||A column may be considered unbraced in a given plan if lateral stability of the structure as a whole is provided by columns only.|
|These columns are not designed to resist lateral loads.||These columns are designed to resist lateral loads.|
|In braced frames lateral loads like wind, earthquake, etc are resisted by some special arrangement like shear wall, bracings or special supports.||In unbraced frames lateral loads like wind, earthquake, etc are resisted by columns.|
|Sidesway or joint translation is not possible in such columns.||Sidesway or joint translation occurs in such columns.|
|These columns have zero value of sway.||These columns are subjected to sway.|
|Most of the steel structures are designed by this method.||Most of the RCC structures are design by this method.|
|These columns are more resistant to Earthquake than unbraced column.||These columns are less resistant to Earthquake than braced column.|
|It is difficult to provide opening between two braced columns.||It is easy to provide opening between two unbraced columns.|
|Used in tube in tube structures where multistory buildings are to be constructed.||Used in RCC framed structures where low story buildings are to be constructed.|
|Structural System having bracing are mostly used in important/special structures.||Structural System without bracing are mostly used in general structures.|
