  16. 16. 4. MAGNITUDES TO BE MEASURED AND FREQUENCY (continued) D THE FREQUENCY RESPONSE CA BE AS IMPORTANT AS RANGE AND AN ACCURACY TOGETHER, BECAUS IF THE RESPONSE ISN’T SUFFICIENT SE THE MEASUREMENTS WON’T BE ACCURATE. FOR ALREADY BUILT RAILWAY R VIADUCTS, THE MAIN MAGNITUDES TO BE MEASU URED ARE THE FOLLOWING:  MOTION IN FOUNDATIONS AND P PIER HEADS MEASURING TILT AGAINST HEADS. BOTH PERPENDICULAR AXES W WITHIN THE HORIZONTAL PLANE. BY MEASURING TILT WE CAN CALCU ULATE ANY DISPLACEMENTS. THIS KIND OF MEASUREMENT CAN BE CON NTINUOUSLY RECORDED ON THE LONG TERM AND DURING TRAIN CIRCUL LATION (IF THE SENSOR ALLOWS IT).16 INECO.
