Abstract

<p>This study aimed numerical investigation on the stiffness reduction of reinforced concrete structures due to moisture loss of concrete. Authors applied the multi-scale thermo-hygral analysis on the shear wall with columns for investigating long term structural performance change subjected to environmental action. Analysis results could reproduce structural response against shear cyclic loading. Scale effect was focused considering existing structures, and it was showed that the speed of stiffness reduction was lower when a RC member was thick.</p>
