🏗️ ACI 318 — | Deflection & Story Drift
In this part, we learn the difference between total lateral displacement, story drift, and drift ratio in reinforced-concrete shear walls.
📐 Key concepts:
• Lateral Deflection
• Story Drift
• Interstory Drift Ratio
• Building Displacement
• Seismic Performance
🔹 Story Drift = Difference between adjacent-floor displacements
🔹 Drift Ratio = Story Drift ÷ Story Height
Understanding drift is essential for evaluating the seismic behavior and serviceability of a
