Analytical Evaluation of Reinforcement Methods for Concrete-Iron Members and Their Economic Implications

Abstract

The primary objective of reinforcement is to enhance the behavior and performance of structural components against seismic forces. Various techniques are available for reinforcing concrete and buildings, with concrete-iron members among the most widely used methods. In this study, load-bearing capacity, flexural strength, shear strength, and design error correction are introduced as key indicators for evaluating different reinforcement methods. The influence of concrete-iron coatings, including steel and fiber-reinforced polymer (FRP) coatings, on these indicators has been assessed. The findings indicate that reinforcing concrete-iron members significantly improves load-bearing capacity, flexural strength, shear strength, and design error correction, while also reducing the usable internal area. In projects where unexpected loads or variations in loading conditions are anticipated, reinforcement can mitigate additional costs associated with structural failures or load mismatches. This is particularly crucial for structures exposed to seismic activities, extreme temperature fluctuations, or dynamic loads.
