DEFLECTIONS IN SLABS ON ELASTIC FOUNDATIONS

THE FUNDAMENTALS OF A NEW METHOD OF SLAB ANALYSIS ARE PRESENTED. THIS NEW ANALYSIS, EMPLOYING A SIMPLE EXTENSION OF MOMENT DISTRIBUTION PRINCIPLES, HAS FURNISHED RESULTS THAT HAVE BEEN SUBSTANTIATED BY ELASTICITY THEORIES AND THE FINITE DIFFERENCE METHODS. THE TECHNIQUE EMPLOYED CONSISTS OF A TRANSFORMATION OF ANY GIVEN SLAB INTO A GRIDWORK OF BEAMS, A SYSTEMATIC LOAD DEFORMATION, AND A SUBSEQUENT DISTRIBUTION OF BENDING MOMENT AND TORSIONAL EFFECTS ON THE GRID. ANALYSES OF SLABS WITH GRID SYSTEMS ARE NOT NEW, BUT A UNIQUENESS IS REALIZED IN THIS ANALOGY BY ASSUMING RIGID AND STRUCTURALLY INDETERMINATE GRID JOINTS THROUGHOUT THE SYSTEM. /AUTHOR/
