AbstractThe movement of two expansion joints is followed experimentally, and the possibility of correlating movement with temperature explored by statistical analysis. The temperature of the air and of the wall at different depths at the joint gave good correlation with the movement. The highest degree of correlation was found in winter, the lowest in summer; movement per degree Fahrenheit (i.e., the slope of the regression line) was twice as much in winter as in summer. Correlation with meterological temperature records for the region was only fair.
