Based on a case study of building structures in operation for over 40 years and had been monitored for 6 years for structural deformation, a method for analyzing length changes of concrete structures in relation to temperature and relative humidity was discussed. The residuals obtained by regression analysis of the length change rate on temperature and regression analysis of the residuals obtained on humidity indicate the possibility of confirming factors other than temperature and relative humidity, i.e., expansion over time, including ASR expansion.
