HORIZONTALLY CURVED BRIDGES SUBJECT TO MOVING LOAD

THE ANALYSIS OF THE DYNAMIC RESPONSE OF SINGLE SPAN, HORIZONTALLY CURVED BRIDGES SUBJECT TO MOVING FORCING SYSTEMS COMPRISED OF SPRUNG AND UNSPRUNG MASS COMPONENTS IS DESCRIBED. THE BRIDGE IS CONSIDERED TO BE A CONTINUOUS, ELASTIC SYSTEM OF THIN-WALLED OPEN CROSS SECTION. AN EXACT SOLUTION TO THE GOVERNING PARTIAL DIFFERENTIAL EQUATIONS IS OBTAINED IN THE FORM OF AN INFINITE SERIES. THE SOLUTION IS PROGRAMMED ON A DIGITAL COMPUTER, AND A COMPARISON IS MADE BETWEEN THE COMPUTED AND MEASURED RESPONSE OF A LABORATORY MODEL. THE EFFECT OF THE MASS AND VELOCITY OF THE LOAD UPON THE DYNAMIC DISPLACEMENTS AND UPON BENDING AND TWISTING MOVEMENTS IS ANALYZED. /AUTHOR/
