Title: STRUCTURAL PERFORMANCE AND LOAD REACTION PATTERNS OF FLEXIBLE ALUMINUM CULVERT
Accession Number: 00203928
Record Type: Component
Abstract: IN NOVEMBER AND DECEMBER 1962 LIVE LOAD TESTS WERE PERFORMED ON SEVEN ALUMINUM CULVERTS RANGING IN SIZE FROM 24 IN. TO 54 IN. STRAIN MEASUREMENTS WERE TAKEN SIMULTANEOUSLY WITH MEASUREMENTS OF SOIL PRESSURE DEVELOPED AROUND THE CULVERT AND WITH MEASUREMENTS OF CULVERT DEFLECTION. ALL TESTING WAS DONE IN SOIL COMPACTED TO 90 PERCENT BY THE MODIFIED AASHO METHOD. ALL APPLIED LOADS WERE AASHO-H20. THIS PAPER PRESENTS THE DATA COLLECTED AND POINTS OUT THE LOAD-SOIL REACTION RELATIONSHIPS FOUND TO EXIST. THE SOIL PRESSURE AND CULVERT STRAIN DISTRIBUTIONS AROUND THE CULVERTS ARE PRESENTED AND SIZE-TO-SIZE AND FILL HEIGHT-TO- FILL HEIGHT COMPARISONS GIVEN. RECOMMENDED MINIMUM FILL HEIGHT TABLES ARE PRESENTED AS A DEVELOPMENT OF THE DATA COLLECTED IN THIS SERIES OF TESTS. THE TESTS INDICATED THAT UNDER CONCENTRATED LOADING AND UNDER CONDITIONS OF HIGH COMPACTION, ALUMINUM CULVERTS INITIALLY TEND TO MOVE TOWARD A SQUARE SHAPE. THE DATA SUPPORTING THIS PROPOSITION ARE PRESENTED AND DISCUSSED. /AUTHOR/
