APPLICATION OF THE MONTE CARLO METHOD TO THE DESIGN OF PRESTRESSED CONCRETE BRIDGES TAKING CONCRETE CREEP AND SHRINKAGE INTO ACCOUNT

PRIMENENIE METODA MONTE-KARLO DLYA RASCHETA PREDNAPRYAZHENNYKH EHLEMENTOV MOSTOV S UCHETOM POLZUCHESTI I USADKI BETONA

THE RESULTS OF THE CALCULATIONS OF PRESTRESSED CONCRETE BRIDGES DEPEND ON NUMEROUS PARAMETERS SOME OF WHICH ARE RANDOM FACTORS: WEATHER AT THE BEGINNING OF CONSTRUCTION OPERATIONS; MODULUS OF ELASTICITY OF THE CONCRETE; FINAL CREEP OF CONCRETE; RATE OF CREEP; FINAL SHRINKAGE AND RATE OF SHRINKAGE; TIME OF THE MANUFACTURE OF THE CROSS-SECTIONS; TIME OF STRESS APPLICATION; REAL PRESTRESSING FORCES. A SIMULATION PROGRAM WAS ESTABLISHED, WHICH SELECTS RANDOMLY A VALUE FOR EACH OF THESE RANDOM PARAMETERS AND CARRIES OUT DETERMINISTIC CALCULATIONS FROM THE VALUES SELECTED. THE AVERAGE VALUES AND STANDARD DEVIATIONS CAN BE DETERMINED FOR STRESSES, LONG-TERM DEFORMATIONS ETC. AN EXAMPLE IS GIVEN OF A BOX GIRDER BRIDGE SECTION BEING SUBJECTED TO DIFFERENT PHASES OF PRESTRESSING. FOR THE COVERING ABSTRACT OF THE CONFERENCE, SEE IRRD ABSTRACT NO. 104872.
