Abstract:

THE DEVELOPMENT OF A RATIONAL METHOD OF ANALYSIS OF ANY SYSTEM MUST INCLUDE THE SELECTION AND ANALYSIS OF A MODEL FOR REALISTIC INPUT PARAMETERS. BASED ON THIS IDEA, A SIMPLE METHOD HAS BEEN DEVELOPED FOR SOLUTION OF OFTEN ENCOUNTERED PROBLEMS OF ENGINEERING PRACTICE INVOLVING SLABS RESTING ON SUBGRADE. THE SLAB IS REPRESENTED BY A PHYSICAL MODEL, WHICH IS HELPFUL IN VISUALIZING THE PROBLEM AND FORMING A SOLUTION. REGARDING SUBGRADE, MOST OF THE AVAILABLE ANALYSES ASSUME IT TO BE A WINKLER MODEL, A PHYSICAL MODEL OF A HEAVY LIQUID, OR A BED OF SPRINGS. IN THIS PAPER THE SOIL IS TREATED AS AN ELASTIC SOLID. WITH THESE TWO MODELS FOR SLAB AND SUBGRADE, A COMPUTER METHOD BASED ON MATRIX ANALYSIS HAS BEEN DEVELOPED. FROM THE SOLUTION OF REACTIVE SUBGRADE PRESSURES, THE DEFLECTIONS ARE THEN SUBSEQUENTLY USED TO COMPUTE STRESSES AND BENDING MOMENTS. TWO EXEMPLARY PROBLEMS, ONE WITH A CORNER LOAD AND ONE WITH A CENTER LOAD, HAVE BEEN INCLUDED. COMPARISON OF THE LATTER WITH THE WINKLER MODEL IS ILLUSTRATED.
