SRC or Tekkotsu Tekkin Konkurīto – 鉄骨鉄筋コンクリート – Real Estate Japan’s Word of the Day

Tekkotsu Tekkin Konkurīto or SRC


  • English definition: Steel Reinforced Concrete. This is considered the building material with the highest earthquake resistance.
  • Often referred to in Japanese as “SRC”.
  • SRC is concrete in which steel is embedded in such a manner that the two materials act together in resisting forces. The reinforcing steel—rods, bars, or mesh—absorbs the tensile, shear, and sometimes the compressive stresses in a concrete structure. (Source: britannica.com)
  • RC stands for “reinforced concrete”. This is concrete that contains embedded steel bars, plates, or fibers that strengthen the material.
