COMPUTER STUDIES OF THE EFFECTS OF TEMPERATURE STRESS OF STEEL BRIDGES DURING THE LAYING OF BITUMINOUS SURFACINGS

RECHNERISCHE UNTERSUCHUNGEN UEBER DIE AUSWIRKUNGEN DER TEMPERATURBEANSPRUCHUNG VON STAHLBRUECKEN BEIM EINBAU BITUMINOESER BELAEGE AUFGRUND VON MESSERGEBNISSEN AN AUSGEWAEHLTEN BEISPIELEN

IN RECENT YEARS, EXTENSIVE TEMPERATURE MEASUREMENTS IN THE STEEL STRUCTURAL COMPONENTS WERE CARRIED OUT BY THE BAST ON SEVERAL LARGE BRIDGES, USING DIFFERENT STATIC SYSTEMS AND DIFFERENT COVERING COMPOSITION DURING THE INSTALLING OF THE BITUMINOUS SURFACING. IN THIS WAY, CONSIDERABLE TEMPERATURE DIFFERENCES WERE FOUND IN THE INDIVIDUAL CROSS-SECTIONS. IT HAS ALSO BEEN SHOWN THAT DEPENDING ON THE INSTALLATION PROCESS AND SPEED OF INSTALLATION MORE OR LESS LARGE STRESSES OCCUR IN THE STATIC PROVISIONALLY PLACED, MAIN SUPPORT ASSEMBLY DUE TO HORIZONTAL BENDING OVER A LARGER LENGTH OF SECTION ON ACCOUNT OF UNEQUAL TEMPERATURE DISTRIBUTION OVER THE WIDTH OF THE BRIDGE. ON THE BASIS OF THESE MEASUREMENTS MATHEMATICAL STUDIES FOR TYPICAL CASES ARE CARRIED OUT REGARDING THE STRESSING OF STEEL CONSTRUCTION. IT IS THEREFORE INTENDED TO DETERMINE THE EFFECT OF DIFFERENT POSSIBILITIES IN THE INSTALLATION OF THE COVERING BY REALISTIC MODIFICATION OF THE MEASURED TEMPERATURE DIFFERENCES.
