MEASUREMENTS OF FORCES EXERTED ON ENGINEERING STRUCTURES

MESURE DES FORCES SUR OUVRAGES D'ART

THE AIM OF THIS RESEARCH IS TO DEVELOP APPARATUS FOR MEASURING THE BEARING PRESSURE OF STRUCTURES IN SERVICE AND, TO DEFINE TEST PROCEDURES AND TO TRAIN TEAMS SPECIALIZED IN OPERATIONAL MEASUREMENTS. IN 1979 IT IS PLANNED: - TO TRY TO FIND A REFERENCE STANDARD AND TO DEVELOP A TEST PROCEDURE FOR THE CALIBRATION OF THE MEASUREMENT SYSTEM; - TO IMPROVE PISTON JACKS; - TO DEVELOP A WEIGHING TEST PROCEDURE AND WEIGHING CELLS FOR CONTINUOUS 24-HOUR RECORDING; - TO IMPROVE THE TECHNIQUE OF CORRECTING MEASUREMENTS (THERMAL GRADIENTS); - TO CONTINUE THE STUDY OF THE POSSIBILITY OF CONDUCTING WEIGHING OPERATIONS ON PILES WITH A 1 PER THOUSAND ACCURACY. FULFIL IF VALID TEST RESULTS ARE TO BE OBTAINED.
