Flexural behavior prediction of a layered composite member with 3D textile reinforced concrete

Abstract

Currently, three-dimensional (3D) textiles are perceived as an attractive construction material that offers a new direction for textile reinforced concrete (TRC) research. In this paper, the textile reinforced layer was strategically applied on the tensile side of a flexural member by taking advantage of the structures of 3D textiles. To simulate the flexural response of layered 3D TRC, an inverse analysis method and closed-form moment–curvature equations were utilized. Simultaneously, bending specimens were fabricated using four different 3D textiles as an experimental method. The composite specimens exhibited significant ductility through deflection hardening. The analytical simulation of layered 3D TRC was compared to the flexural experimental results, and good agreement was found. Furthermore, the applicability of precast 3D TRC was presented using the spacer yarns of the textiles as anchors between the layers.
