ON THE TRANSVERSE FREE VIBRATIONS OF BEAM-SLAB TYPE HIGHWAY BRIDGE

ANALYSIS OF VIBRATION PROBLEMS DEALING WITH PLANT EIGENFUNCTIONS AND TRANSCENDENTAL EQUATIONS INVOLVES RATHER TEDIOUS TRIAL AND ERROR SOLUTIONS TO TRIGONOMETRIC AND HYPERBOLIC FUNCTIONS. A MODIFIED APPROACH BASED ON THE ORTHOTROPIC PLATE THEORY FOR COMPUTING THE NATURAL FREQUENCIES OF BRIDGE SLABS IS PRESENTED THROUGH A SET OF EMPIRICAL RELATIONS BETWEEN THE PLATE PARAMETERS. A GENERAL OUTLINE OF THE ANALYTICAL PROCEDURE AND COMPUTED VALUES OF NATURAL FREQUENCIES OF VIBRATION OF SUCH SLABS FOR A WIDE RANGE OF PARAMETERS ARE GIVEN. WHENEVER POSSIBLE, RESULTS FROM THE PRESENT INVESTIGATION ARE COMPARED WITH THOSE OBTAINED BY OTHER METHODS; GOOD AGREEMENTS ARE OBTAINED. /AUTHOR/
