Title:

PROBLEMS OF SKEW IN CONCRETE BRIDGE DESIGN

Accession Number:

00208204

Record Type:

Monograph

Abstract:

THE PROBLEMS OF SKEW IN CONCRETE BRIDGE DESIGN ARE DISCUSSED AGAINST THE BACKGROUND OF AVAILABLE ANALYTICAL AND EXPERIMENTAL METHODS OF SOLUTION. THE INADEQUACY OF THE ANALYTICAL METHODS IS EMPHASIZED BUT THE GREAT POTENTIALITIES AND VERSATILITY OF THE FINITE ELEMENT METHOD ARE RECOGNIZED. SPECIAL CONSIDERATION IS GIVEN TO THE ASSESSMENT OF STRESSES NEAR THE OBTUSE CORNERS AND IN STIFFENING BEAMS AS WELL AS THE INFLUENCE OF POISSON'S RATIO ON THE STRESS DISTRIBUTION. THE IMPORTANCE OF CONSIDERING STRUCTURAL MODEL ANALYSIS AND TESTING AS A DESIGN TOOL, AND THE AUGMENTING ASPECTS OF ANALYTICAL AND EXPERIMENTAL METHODS ARE DISCUSSED. DESIGN CONSIDERATIONS PECULIAR TO SKEW BRIDGE DECKS ARE ELABORATED UPON. THE CALCULATION OF MOMENTS AND REACTIONS, EFFECTS GENERATED BY VARIATIONS IN THE NUMBER, SPACING, AND FLEXIBILITY OF SUPPORTS, THE PRESENCE OF A PRESTRESSING FORCE AND THE PROPORTIONING OF FLEXURAL REINFORCEMENT ARE CONSIDERED. ELASTIC, ULTIMATE STRENGTH AND LIMIT DESIGN PROCEDURES ARE BRIEFLY DISCUSSED AND THE NEED FOR FURTHER RESEARCH IS EMPHASIZED. THE POSSIBILITY OF DEVELOPING DESIGN AIDS IN FORMS OF TABLES AND GRAPHS IS BRIEFLY EXAMINED. IT IS PROPOSED THAT CLAUSES PERTAINING TO THE PROBLEM OF SKEW BE INCORPORATED INTO EXISTING BRIDGE SPECIFICATIONS. /CGRA/
