THE COMPUTATION OF STRAIN IN CONCRETE USING STRAIN METER DATA

THE COMPUTATIONAL PROCEDURE USED TO REDUCE DATA FROM EMBEDDED STRAIN METERS TO STRAIN IN THE SURROUNDING CONCRETE IS DESCRIBED IN DETAIL. AN ILLUSTRATIVE EXAMPLE SHOWS THE STEPS IN THE COMPUTATION OF STRAIN FROM DATA PROVIDED BY AN ARBITRARILY CHOSEN STRAIN METER OF A STANDARD GROUP IN A BUREAU OF RECLAMATION DAM. DESCRIPTIONS OF A CARLSON STRAIN METER AND A TEST SET USED TO READ SUCH METERS ARE INCLUDED. THE RECORD OF THE PREINSTALLATION TESTS OF THE METER USED IN THE EXAMPLE IS INCLUDED TO ILLUSTRATE THE USES OF THAT DATA IN THE COMPUTATIONS. ARITHMETICAL COMPUTATIONS SHOWN IN THE EXAMPLE WERE MADE BY USE OF A DESK CALCULATOR. AUTOMATIC DATA PROCESSING (ADP) METHODS USE ESSENTIALLY THE SAME PROCEDURES. AN APPENDIX DESCRIBING A MORE ACCURATE METHOD OF DISTRIBUTING EXPERIMENTAL ERRORS IS INCLUDED, WITH THE EXPLANATION THAT IT IS PRACTICAL ONLY FOR USE IN ADP METHODS. /AUTHOR/
