STRAIN METERS AND STRESS METERS FOR EMBEDMENT IN MODELS OF CONCRETE STRUCTURES. REPORT 1. SUMMARY OF INFORMATION AVAILABLE AS OF MARCH 1, 1967
A SUMMARY IS GIVEN OF THE RESULTS OF AN EXTENSIVE LITERATURE REVIEW AND A WORLDWIDE SURVEY TO DEVELOP INFORMATION ON SMALL, EMBEDDED STRESS METERS AND STRAIN METERS SUITABLE FOR MODEL WORK AND LONG-TERM INVESTIGATIONS. FOLLOWING A DISCUSSION OF GENERAL PROBLEMS OF INTERNAL STRAIN AND STRESS MEASUREMENT IN CONCRETE, INCLUDING A BRIEF REVIEW OF THE ADVANTAGES AND DISADVANTAGES OF VARIOUS SYSTEMS OF MEASUREMENT, NUMEROUS PARTICULAR METERS ARE DESCRIBED IN DETAIL, AND THEIR APPLICABILITY TO MODEL WORK IS TENTATIVELY ASSESSED. THE INFORMATION COLLECTED REVEALS A LACK OF SMALL, EMBEDDED METERS SUITABLE FOR LONG-TERM MODEL STUDIES. A NUMBER OF OTHER SYSTEMS OF MEASUREMENT (INDUCTANCE-CAPACITANCE, SEMICONDUCTOR, HYDRAULIC, AND PNEUMATIC METERS) THAT APPEAR RATHER PROMISING FOR INTERNAL STRESS AND STRAIN MEASUREMENT IN CONCRETE HAVE HARDLY BEEN INVESTIGATED TO DATE. BASED ON THE RESULTS OF THIS PRELIMINARY STUDY, IT IS CONCLUDED THAT FURTHER EFFORTS TO SELECT OR DEVELOP SUITABLE INSTRUMENTATION SHOULD CONCENTRATE ON THE EVALUATION AND IMPROVEMENT OF BONDED WIRE METERS, ON THE DEVELOPMENT OF NEW INDUCTANCE AND SEMICONDUCTOR METERS, AND ON THE USE OF EXISTING SMALL ACOUSTIC METERS. /AUTHOR/
