WARPING STRESSES AND DEFLECTIONS IN CONCRETE PAVEMENTS: PART II

A SOLUTION HAS BEEN OBTAINED FOR STRESSES AND DEFLECTIONS OF CONCRETE SLABS ON GROUND SUBJECTED TO TEMPERATURES AND/OR MOISTURE CONTENTS WHICH DECREASE LINEARLY WITH THE DEPTH OF THE SLAB. THE DERIVED EQUATIONS WERE PROGRAMMED WITH THE AID OF A COMPILER AND SOLUTIONS WERE OBTAINED FROM THE DATATRON 204 DIGITAL COMPUTER. NOMOGRAPHS ARE PRESENTED WHICH GIVE THE RATIOS OF THE MAXIMUM STRESS TO THE MODULUS OF RUPTURE FOR A WIDE RANGE OF ENVIRONMENTAL GRADIENTS AND FOR VARIOUS COMBINATIONS OF SLAB SIZES AND THICKNESSES. THE SOLUTIONS ARE OBTAINED FOR THE CRITICAL CONDITION WHICH DEVELOPS WHEN THE SLAB IS ONLY PARTIALLY SUPPORTED. A 12- BY 25-FT SLAB 8 IN. THICK, RESTING ON A SOIL-CEMENT SUBBASE, WAS APPROPRIATELY INSTRUMENTED AND SUBJECTED TO TEMPERATURE GRADIENTS UNDER CONTROLLED CONDITIONS. COMPARISONS BETWEEN COMPUTED AND MEASURED DEFLECTIONS CONFIRM THE VALIDITY OF THE NEW THEORY. /AUTHOR/
