Based on the research of normal confined concrete (NCC), regional confined concrete (RCC) was proposed years ago by authors. With the introduction of regional confinement concept, different mechanical properties, failure mode and energy dispatching property developed in the regional confined concrete elements. Experimental researches have been carried out during the past years on the elements under various loads, including beams under moments, short beams under shears, short columns under axial loads, middle long columns under eccentric loads, middle long columns under axial loads and columns under cycling loads. Experimental results indicated that RCC elements are more ductile, have better load carrying capacity and larger energy dispatch capacity than that of NCC elements. Stress-strain relationship of RCC, integrated confinement factor and some computation expressions for elements under various loads are proposed. Pilot projects have been conducted and regional confined concrete structures are ready for service.
