This paper deals with resources circulation-oriented ecomaterials design of building structural composite components of continuous fiber reinforced concrete (FRPRC), based upon conceptual design and experimental date of structural behaviors and recyclability. Newly developed lightweight, high strength and high elastic, highly corrosion-resistant, and also thermally-recyclable non-metallic FRP reinforcements made of thermoplastic resins (FRTP), combined with lightweight, high strength concrete, improve material efficiency very much, compared with ordinary RC, by reducing the sectional areas and expanding the spans of columns and beams, and also to be recycled after designed service life, contrary to ordinary FRTS reinforcements made of thermosetting resins.
