TRC comprises an innovative composite material consisting of fabric meshes made of long fibre yarns (e.g carbon, glass, aramid or basalt) arranged in at least two (typically orthogonal) directions and embedded in a cementitious fine-grained matrix. Two types of reinforced concrete specimens were considered: the first one included 22 beam-type specimens incorporating flat TRC formworks, whereas the second included 11 prismatic column-type specimens cast into permanent precast TRC shafts. Moment and deflection values at first-crack, steel yielding (where applicable) and ultimate for the beam-type specimens were analytically derived based on a proposed simplified approximation of strain distribution across a fibre roving. Based on the results of this study SiP TRC formwork elements comprise an attractive system for hybrid construction practices.

TRC comprises an innovative composite material consisting of fabric meshes made of long woven, knitted or even unwoven fibre yarns (e.g. carbon, glass or aramid) in at least two (typically orthogonal) directions embedded in a cementitious matrix (mortar or fine-grained concrete). The experimental investigation described in this study was carried out on two types of reinforced concrete specimens: the first one included 22 beam-type specimens incorporating flatTRC stay-in-place formworks and the second one included 11 prismatic column-type specimens cast into permanent precast TRC shafts.
