AN ACCURATE DESIGN METHOD FOR BURIED FLEXIBLE CONDUIT STRUCTURES

THE DESIGN METHOD PRESENTED EVALUATES THE STRUCTURAL PERFORMANCE OF BURIED FLEXIBLE STRUCTURES OF ANY CROSS SECTIONAL SHAPE HAVING A VERTICAL AXIS OF SYMMETRY. IT IS APPROPRIATE TO ANY STRUCTURE HAVING A LINEAR STRESS-STRAIN RELATIONSHIP, SUCH AS ALUMINUM, STEEL OR CONCRETE. PERIPHERAL VARIATIONS OF THE MOMENT OF INERTIA OF THE WALL CROSS-SECTION CAN ALSO BE INVESTIGATED. VARIATIONS OF SOIL DENSITY, SOIL STRESS-STRAIN RELATIONSHIPS, ACTIVE PRESSURES, SURFACE LIVE LOADS AND IMPACT CAN BE EVALUATED. THE NON- LINEAR MATHEMATICAL SOLUTIONS INVOLVED IN THE ANALYSIS WERE PROGRAMMED ON A 7094 COMPUTER FOR RAPID SOLUTION. BECAUSE OF THE COMPLEX MATHEMATICS, MANUAL SOLUTIONS ARE NOT PRACTICAL. VERIFICATION OF DESIGN CONCEPTS WERE MADE BY INSTRUMENTED FIELD TESTS /CONDUCTED BY KAISER ALUMINUMS PRODUCT DEVELOP- MENT ENGINEERS/ AND BY SEVERAL YEARS OF FIELD EVALUATION OF CONTRACTOR-INSTALLED STRUCTURES OF ALL TYPED, SIZES AND COVER. APPROXIMATELY ONE HUNDRED STRUCTURES WERE MONITORED IN THIS PROGRAM, AND ALL CONFIRMED THE VALIDITY AND INHERENT CONSERVATISM OF THE DESIGN METHOD PRESENTED.
