A STUDY OF SOIL-STRUCTURE INTERACTION: REINFORCED CONCRETE CULVERT PIPES

FIELD MEASUREMENTS WERE MADE ON 7 REINFORCED CONCRETE CULVERTS TO DETERMINE THEIR DEFLECTIONS. THE MEASURED DEFLECTIONS HAVE AN AVERAGE VALUE OF 0.0007 TIMES THE DIAMETER AND A MAXIMUM VALUE OF 0.003 TIMES THE DIAMETER. ANALYSIS HAS SHOWN THAT THE FIELD PERFORMANCE OF REINFORCED CONCRETE CULVERT PIPES IS ESSENTIALLY THAT OF A RIGID TUBE. CALCULATIONS BY THE FINITE ELEMENT METHOD, USING THE SOIL MODULUS AS MEASURED IN LABORATORY CONFINED COMPRESSION TESTS, HAVE GIVEN DEFLECTIONS THAT ARE IN AGREEMENT WITH OBSERVED VALUES. THE AVAILABILITY OF THE FINITE ELEMENT METHOD MAKES IT POSSIBLE TO INTRODUCE A RATIONAL DESIGN CONCEPT BASED ON THE CONDITION THAT THE CULVERT BE DESIGNED TO WITHSTAND A CERTAIN BENDING MOMENT AT THE CRITICAL SECTION. /AUTHOR/
