Vulnerability and Sensitivity Assessment of RC Structure with Uncertainity in Material Properties

The importance of uncertainties in material properties for building behavior needs to be brought into focus because the reliability and robustness of behavior predictions under uncertainty have not been well recognized. The assessment of seismic risk of structures is subjected to uncertainty, and therefore material properties need to be considered. The seismic susceptibility of structures (RC) varies considerably due to uncertainties in material strengths developed by construction procedures. To address this, performance-based analysis and designs are being intensively researched, evaluating the variability in material strengths and their specific effects on seismic susceptibility through fragility estimates and tornado diagram analysis. The results show that the variations in material thickness affect the structural response in a significant way. The parameters used to comprehend the structural response have shown that changes in material strength must be vigilantly well thought-out.
