CENTRICALLY LOADED INFINITE STRIP ON A SINGLE-LAYER ELASTIC FOUNDATION-SOLUTION IN CLOSED FORM ACCORDING TO THE BOUSSINESQ THEORY

A SURVEY OF METHODS OF CALCULATING THE PRESSURE DISTRIBUTION BETWEEN AN ELASTIC BEAM AND AN ELASTIC FOUNDATION IS GIVEN. THE METHODS ARE BASED ON EITHER THE WINKLER OR THE BOUSSINESQ MODEL OF THE SUBGRADE REACTION. IN SOME CASES THE MODELS ARE MODIFIED. THE LIMITATIONS AND VALIDITY OF THE DIFFERENT METHODS ARE DISCUSSED. THE CASE OF A DISTRIBUTED LOAD APPLIED AT THE CENTER OF AN INFINITE STRIP, RESTING ON A SINGLE LAYER ELASTIC FOUNDATION, IS INVESTIGATED BY MEANS OF THE BOUSSINESQ THEORY. THE RESULTS ARE GIVEN IN CLOSED FORM AND PRESENTED IN A DIAGRAM GIVING MAXIMUM CONTACT PRESSURE, MAXIMUM DEFLECTION, AND MAXIMUM BENDING MOMENT. /TRRL/
