INFLUENCE FACTORS FOR BENDING MOMENTS AND SHEARING FORCES OF ORTHOTROPIC PLATES IN DISCONTINUOUS SYSTEMS

ORTHOTROPE PLATTEN - EINFLUSSWERTE FUER BIEGEMOMENTE UND QUERKRAEFTE DISKONTINUIERLICHER SYSTEME

THE ORTHOTROPIC PLATES IN STEEL BRIDGE STRUCTURES FORM PART OF A DISCONTINUOUS SYSTEM. THE TRANSVERSE BEAMS OF THE BRIDGE DECK WHICH ARE THE MAIN BEAMS OF THE ORTHOTROPIC PLATE ARE GENERALLY SPACED RELATIVELY FAR APART. THE MAIN LONGITUDINAL BRIDGE GIRDERS WHICH FORM THE TRANSVERSE BEAMS OF THE PLATE ARE USUALLY PLACED FAIRLY CLOSE TOGETHER. THE DISCONTINUITY OF THE TRANSVERSE BRIDGE GIRDERS WAS USUALLY NEGLECTED IN THEORETICAL ANALYSES OF THE ORTHOTROPIC PLATE. THE AIM OF THE PRESENT BOOK IS TO TAKE ACCURATE ACCOUNT OF THIS DISCONTINUITY OF THE TRANSVERSE BRIDGE BEAMS. BECAUSE OF THE CLOSE SPACING OF THE LONGITUDINAL BRIDGE GIRDERS THEIR DISCONTINUITY IS IGNORED. THEORETICAL SOLUTIONS ALWAYS RESULT IN INFINITE VALUES FOR BENDING MOMENTS AND SHEARING FORCES AT THE POINT OF APPLICATION OF THE LOAD. TAKING ACCOUNT OF THE DISCONTINUITY HOWEVER ELIMINATES THE SINGULARITIES AND RESULTS IN FINITE VALUES OF BENDING MOMENTS AND SHEARING FORCES. PREVIOUS THEORETICAL SOLUTIONS FOR ORTHOTROPIC PLATES HAVE GIVEN INFLUENCE SURFACES ONLY FOR THE BENDING MOMENTS AT MIDSPAN AND FOR THE SHEARING FORCES AT THE EDGE OF THE SUPPORTS OF THE PLATE. IN CONTRAST THE PRESENT WORK ALSO GIVES VALUES OF MOMENTS AND SHEARS FOR THE POINT 0,2 L (INDEX X).
