Abstract: A parametric model for simulation of tensile behaviour of cement-based composites is used to correlate the stress strain constitutive response with flexural load carrying capacity of strain hardening cement composites. This procedure can also be used as a design approach.
Using a back-calculation approach, the results of tensile experiments of composites are converted to a parametric model of strain hardening material and closed form equations for representation of flexural response of sections are obtained. Results are then implemented as average moment-curvature relationships in the structural design and analysis of one way and two way flexural elements using yield line analysis approaches. Correlation of material properties with simplified design equations is shown. Independent experimental results obtained in-house and from literature are used to verify the model using textile Reinforced Concrete with alkali resistant (AR) glass textile reinforced concrete and ECC Composites. A generalized approach for the design equations using a plastic analysis approach is shown
