Zhang's Model (Bridge inspection methodology)

Zhang's Model is a systematic approach used to inspect bridges by categorizing different types of structural issues based on their causes and symptoms. It helps inspectors identify problems, such as cracks or corrosion, by analyzing how these defects relate to specific structural components or load conditions. This model emphasizes understanding the root causes behind observable damage, enabling targeted maintenance and improved safety. Essentially, it acts as a framework for organizing inspection findings, making it easier for engineers to prioritize repairs and ensure the long-term integrity of the bridge.
