究で解明されている。2. Description of the Related Art Reinforced concrete buildings have been seriously damaged by recent major earthquakes both inside and outside, and shear failure of columns has been pointed out as the primary cause of the damage. And
It has been clarified that the cause of increasing the shear failure is the repeated repeated deformation many times during a strong earthquake, which prevents the reinforced concrete column from shear failure against such a repeated force, and stabilizes and restores the restoring force characteristics. Recently, it has been clarified that it is optimal to effectively restrain the concrete (core concrete) in the area surrounded by the main bars in order to secure the strength.
【０００３】このような考えに基いて、柱の外周に鋼板
