Influence of Transversal Connections on the Mechanical Behavior of 3D-Textile-Reinforced Cements (TRCs): Effect on Plate Specimens

Abstract

Three-dimensional textiles can offer improved mechanical performances compared with planar alternatives when used as reinforcement in Textile-Reinforced Cements (TRCs). The increased post-cracking stiffness observed in unidirectional flexural applications is attributed to the enhanced anchorage provided by the transversal connections in 3D textiles. Currently, this effect has only been observed in unidirectional flexural applications and not in tension. To identify potential anchorage mechanisms in other loading conditions, this research study presents a bidirectional flexural campaign on plate specimens supported in four points. A configuration with 3D reinforcement is compared to a 2D-equivalent configuration as well as numerical simulations.
