INVESTIGATION OF A TORSION POST-BEAM RAIL TYPE OF BRIDGE RAILING

RESULTS OF AN INVESTIGATION OF A NEW CONCEPT FOR HIGHWAY BRIDGE RAILINGS INCORPORATING TORSION POSTS ARE REPORTED. STRUCTURAL ANALYSES AND THE RESULTS OF A COMPUTER SIMULATION MODEL OF VEHICLE IMPACT WERE USED TO SUPPORT THE DESIGN OF BRIDGE RAIL CONFIGURATIONS AIMED AT ACHIEVING ELASTIC DEFLECTIONS AND IMPROVED PERFORMANCE. FULL-SCALE CRASH TESTS OF TWO EXPERIMENTAL TORSION POST BRIDGE RAILS WERE CONDUCTED. INSTRUMENTATION EMPLOYED TO MEASURE DETAILED DYNAMIC RESPONSES OF THE VEHICLES, DUMMY OCCUPANT, AND BRIDGE RAILINGS DURING IMPACT ARE DESCRIBED. BRIDGE RAIL PERFORMANCE AS DETERMINED FROM THE TESTS IS EVALUATED WITH RESPECT TO A SET OF RECOMMENDED REQUIREMENTS DERIVED ON THE BASIS OF RESULTS REPORTED IN THE LITERATURE FOR OTHER TYPES OF BRIDGE RAILS. /AUTHOR/
