BEHAVIOR OF AN ALUMINUM STRUCTURAL PLATE CULVERT

A 28-ft 6-in. span, 17-ft 10-in. high, corrugated aluminum culvert was instrumented to obtain measurements of strain and displacement during backfilling and under static live load. Values of circumferential bending moment and thrust at 16 locations spaced around the structure's circumference at midspan are reported for each 2 ft of backfill from the springline to 2 ft over the crown. Despite bending moments 70 percent of the fully plastic value, and stresses that exceed the nominal yield point of the aluminum, it is concluded that the structural behavior is satisfactory. Discrepancies between measured values and design predictions are discussed. (FHWA)
