Textile-reinforced concrete: Structural behavior

Abstract This chapter illuminates specific features of the structural behavior occurring in textile-reinforced concrete (TRC) applications and relates them to the underlying material behavior. After explaining and discussing the underlying phenomenon of stress redistribution on a simplified discrete system, the redistribution effects affecting the structural response are analyzed in detail for two real-world examples. The two presented case studies of shell structures, one numerical and one experimental, contribute to deeper understanding of the relation between the properties of the composite and the structural response. The first case study presents a numerical analysis with the help of an anisotropic damage material model that was tailored for the simulation of TRC shells. The second case study shows a detailed experimental analysis of a full-sized specimen of a barrel-vault shell providing valuable feedback and validation of the dimensioning and assessment approach presented in the previous chapter. The performed studies indicate a positive effect of the strain-hardening behavior in frequent structural configurations, namely in shells with smooth in-plane tensile strain gradients. Understanding of these redistribution effects can contribute to increased structural reserves and, consequently, to an increased safety of design.
