Structure ties in reinforced concrete are used in columns. There are a number of reasons for using relations. The main reasons for using relations in the column are the following.
- To hold the longitudinal bars in position while the concrete is being put in the shapes.
- To avoid the longitudinal plates, which are highly stressed, from buckling outwards by breaching the thin concrete shield.
There are many guidelines in the civil engineering code for using links in columns. The design engineers must be conscious of this code requirement during the design of a concrete base.
Spiral Column
Concrete, spiral-reinforced columns can withstand more loads than the tied columns. This phenomenon occurs because when load eccentricities are small, spirally reinforced columns exhibit greater toughness, greater ductility than the tied column.
Hence, civil engineering practitioners are required to use spiral support instead of connections in reinforced concrete columns whenever feasible.
