Abstract

This article provides data on the static behavior of reinforced concrete at room and low temperature including, strength, ductility, and crack widths of the reinforced concrete. The experimental data on the application of digital image correlation (DIC) or particle image velocimetry (PIV) in measuring crack widths and the accuracy and precision of DIC/PIV method with temperature variations when is used for measuring strains is provided as well.

Highlights

  • This article provides data on the static behavior of reinforced concrete at room and low temperature including, strength, ductility, and crack widths of the reinforced concrete

  • The experimental data on the application of digital image correlation (DIC) or particle image velocimetry (PIV) in measuring crack widths and the accuracy and precision of DIC/PIV method with temperature variations when is used for measuring strains is provided as well

  • The load values were measured by the built-in load cells of the electric and hydraulic rams, and deflection values were measured by linear potentiometers (LP) placed at midspan

Processed and Analyzed Room and Low temperature, thermal gradient, temperature variations, monotonic load, sustained load, 10 load cycles Effects of low temperature on the static behaviour of reinforced concrete beams with temperature differentials Precision and accuracy of DIC/PIV method with temperature variations Kingston, Ontario, Canada. The experimental data on temperature variations, and thermal gradient due to solar radiation on the structural behavior of concrete bridges can be used in “design of concrete structures for temperature”. The experimental data on the accuracy and precision of DIC camera system in measuring strains at different temperatures determined that the strain data that is obtained through this method needs to be calibrated through independent calibration tests. The beams had temperature differentials over their depth and were tested at room and low temperature under monotonic load, sustained load and few load cycles (Table 1)
