Engineers analyze box culverts as a closed rigid frame. The structural analysis generally follows these steps: Step 1: Geometry and Material Properties Define the clear span ( ), clear height ( ), thickness of slabs ( ), thickness of walls ( ), concrete compressive strength ( fc′f sub c prime ), and steel yield strength ( Step 2: Load Evaluation Span, Rise, Soil Density, Concrete Grade (M30/M40), Steel
