Abstract
<p> Precise practical estimation of the expansive strain distribution in cross-sectional dimension is important for effective use of CPC(Chemically pre-stressed concrete) members, but previous studies have reported only the expansive strain distribution of CPC members having symmetrical arrangement of reinforcing bars and cross-sectional dimensions. In this study, we report the estimation method and the experimental results of the expansive strain distribution of CPC members with non-symmetrical rebar arrangement in T-shaped and L-shaped cross sections. The value of the expansive strain estimated by the proposed cross-sectional analysis from the expansive strain of the JIS specimen is goodly corresponded with the experimental value using the Work-done concept.</p>
