ABSTRACT
This paper presents an experimental programme to study the residual compressive stress-strain relationship of Strain-Hardening Cementitious Composite (SHCC) with hybrid PVA and steel fibres after exposure to 30, 200, 400, 600 and 800°C. The results showed that SHCC had a smaller decrease in residual strength and elastic modulus than ordinary concrete with temperature rising. Based on the experimental results, compressive stress-strain constitutive equations for SHCC after exposure to 30, 200, 400, 600 and 800°C were proposed via regression analysis. The constitutive equations match the experimental stress-strain curves well and can be applied for residual loading capacity of SHCC structural members after subjected to known temperature effect.
