Abstract (AI)
Reinforced Concrete (RC) durability is a crucial feature to estimate the long-term quality and structural performance. Since life span estimation is vital for maintenance resource planning, a degradation model of RC component extracts by updating the status of structures and trending the components’ state over time in terms of durability. Surface erosion, spalling, cracks, and other expose defects on the RC component lead to increase factors adversely affecting concrete durability in structures. This research presents an approach based on automated visualization for extracting quantitative indexes beside or instead of visual inspection without subjective interspersion of humans or probable human errors during the inspection. The durability index (D_i) will extract based on damage probability and its growth in order to extract the severity of failure and risk. Measurement operation by automated software has been double-checked by manual measurement tools, and data will verify randomly in this method. The result shows damage growth in this load-bearing component by 24 percentages over the definite time. According to degradation models, it shows this component may pass the relative thresholds as a limit state of operation to fail. This significant difference between expected time and designing time determines the D_i equal to 5 out of 10.
Key Findings
1
An automated visualization approach extracts quantitative reinforced-concrete durability indexes while reducing subjective judgment and potential human inspection errors.
2
Automated measurements were cross-checked with manual measurement tools and randomly verified to support measurement reliability.
3
Degradation modeling indicates the component may exceed operational limit-state thresholds, yielding a durability index of 5 out of 10.
4
The durability index is derived from damage probability and damage growth to quantify failure severity and structural risk.
5
The investigated load-bearing component exhibited 24% damage growth over the specified period.
