Proof Testing of a Structural Plate Pipe with Varying Bedding and Backfill Parameters. Section 3. Analysis of Internal Pipe Strains

摘要

A 120-in (3.05-m), 12-gauge steel, structural plate pipe, embedded in an embankment under 188 ft (57 m) of overfill, was heavily instrumented and tested for structural behavior under the imposed earth loads. This section of the report describes the reduction of measured culvert wall strain data and the calculation of moments and thrusts acting on the culvert. Tabular and graphic output from a simplified plastic model of the culvert is presented.
