This is a high technique.
  • Steel reinforced concrete structure can be called the fusion of steel structure and steel concrete structure. It is the construction method that can make the most robust structure by supplementing the structural shortcomings that cannot be solved with steel only with steel and concrete. However, there are still disadvantages of the cost increase due to the use of steel frame and the need to install formwork and cast concrete in the field.
