Innovative idea to increase bearing capacity and ductility of concrete columns by using rectangular spiral reinforcement

The columns are one of the most important members of the construction structures, which is responsible for the bearing and transfer of loads to the structure. The behavior of compressive RC members is generally based on the concrete strength and ductility of concrete which with confining concrete ca...
