Abstract

Back-calculation procedures are used to obtain uniaxial tensile properties of cement composites from closed loop flexural tests. The proposed methodology uses a forward calculation of obtaining load deflection results based on tensile data in conjunction with crack localization rules. A closed form solution for moment-curvature and load deflection response is obtained using these material parameters. Test results are applied to a series of strain hardening composites to obtain material parameters for polymeric fiber reinforced concrete samples. Test results are compared with data reported for Average Residual tensile Strength (ARS) obtained from ASTM tests such as ASTM C1399 and C1609 and a correlation between the ARS and proposed post-peak strength are obtained. Results point out to the un-conservative nature of reporting the material properties data using the ASTM recommended test procedures.
