In-Situ Stress Measurements in Concrete: A Simple and Reliable Technique to Verify Condition Of Post-Tensioning

Provided with information regarding the existing state of stress in a structural member, the engineer can estimate the extent of deterioration, update safety factors, forecast the probable evolution of the structure and optimize the design of strengthening or repair solutions. This paper presents a recently developed, easily implemented technique designed to improve the precision of in-situ stress measurement in concrete. The technique has passed several trials conducted by various independent organizations in several countries, and has been successfully implemented on several projects internationally. This paper describes the background and the principles of that stress measurement technique, and presents case studies of several projects.
