COMPARATIVE STUDIES ON CORRUGATED METAL CULVERT PIPES

THE PROJECT CONSTITUTES THE INITIAL STAGE OF A THREE-PHASE PROGRAM OF RESEARCH INTO THE SOIL-STRUCTURE INTERACTION ATTAINED IN CULVERT PIPE STRUCTURES. THE OBJECTIVES OF PHASE I WERE TO /1/ DEVELOP METHODS OF TEST FOR SIGNIFICANT STRUCTURAL PROPERTIES OF CORRUGATED METAL CULVERT SECTIONS; /2/ TO ASCERTAIN THE CONTROLLING GEOMETRIC AND MECHANICAL PARAMETERS OF SUCH SECTIONS; AND /3/ TO PERFORM COMPARATIVE TESTS AND EVALUATE THE STRUCTURAL PERFORMANCE OF TYPICAL METAL CULVERT SECTIONS AVAILABLE. THREE TYPES OF FLEXIBLE PIPE WERE INVESTIGATED' SPIRAL CORRUGATED METAL PIPE, RIVETED CORRUGATED METAL PIPE AND SPOT-WELDED CORRUGATED METAL PIPE. TESTS PERFORMED' WALL STRENGTH TESTS, TWO-EDGE BEARING TESTS, SHORT COLUMN TESTS, AND BEAM TESTS. THE FOLLOWING CONCLUSIONS WERE DRAWN BASED ON WALL STRENGTH' SPIRAL PIPES IN GENERAL DEVELOPED SUFFICIENT RESISTANCE IN THE SEAMS TO CAUSE FAILURE BY WALL BUCKLING. THE HELIX ANGLE OF THE SPIRAL PIPE DID NOT HAVE ANY SIGNIFICANT EFFECT ON ULTIMATE LOAD AT ANGLES OF 8 DEGREES OR LESS, WITH ANGLES GREATER THAN 8 DEGREES THERE WAS A DEFINITE INCREASE IN GREATER THAN 8 DEGREES THERE WAS A DEFINITE DECREASE IN ULTIMATE LOAD PER FOOT THE SPIRAL PIPE WITH THE 1/2- BY 2- INCH CORRUGATION WAS ABOUT 37 PERCENT STRONGER THAN THE WELDED WHILE THE 1/2- BY 2-2/3-INCH CORRUGATION WAS 10 PERCENT WEAKER THAN THE WELDED PIPE OF THE SAME GAGE THE RIVETED PIPE SPECIMENS WERE APPROXIMATELY 15 PERCENT WEAKER THAN THE WELDED SPECIMENS OF THE SAME GAGE AND DIAMETER. THE FOLLOWING ARE THE CONCLUSIONS FROM THE TWO-EDGE BEARING TEST ' THE EXPERIMENTAL VALUES OF E1 FELL APPROXIMATELY 14 PERCENT BELOW THE ANALYTICAL VALUES; THE RIVETED AND WELDED PIPE ARE PRACTICALLY EQUAL THE EXPERIMENTAL E1 OF THE SPIRAL PIPE WITH 1/2- BY 2-INCH CORRUGATION WAS ABOUT 25 PERCENT BELOW THE COMPARABLE RIVETED OR WELDED PIPES THE SPIRAL PIPE WITH THE 1/2- BY 2-2/3-INCH CORRUGATION WAS ABOUT 31 PERCENT BELOW THE RIVETED OR WELDED PIPES THE VARIATION OF THE SPIRAL PIPE VALUE OF E1 FROM THE RIVETED AND WELDED PIPE VALUES DECREASED AS THE DIAMETER DECREASED. THE PRINCIPAL CONCLUSION FROM THE BEAM TESTS IS' THE WELDED, RIVETED AND 2-2/3 PITCH SPIRAL PIPE SPECIMENS WERE, FOR ALL PRACTICAL PURPOSES, EQUAL. THE SPIRAL PIPE WITH THE 1/2- BY 2-INCH CORRUGATION WAS APPROXIMATELY 25 PERCENT INFERIOR TO THE OTHER TYPES OF PIPE. /BPR/
