- Abstract
- The health of concrete structures is important because collapse of these structures can cause damage for humans. This paper presents an analytical model for calculation of crack widths in structural concrete members using Internet of Things. The model is mathematically derived from the actual bond stress-slip relationship between the reinforcing steel and the surrounding concrete. The relationships summarized in CEB-FIP Model Code 1990 and Eurocode 2 are used in this study together with the numerical analysis result of a linear slip distribution along the interface at the stabilized cracking stage. With these, the actual strains of the steel and the concrete are integrated respectively along the embedment length between the adjacent cracks to obtain the difference in the axial elongation. This model is applied to the test results available in literature. The predicted values are shown to be in agreement with the experimentally measured data.
