Parametric Study of Drilling Method Performed on One-Way Post-Tensioned Slabs

Abstract Determination of the stress state in concrete structures is a very important, but difficult task. In case new structures, it possible to easily instal measurement instruments which can provide important data as part real-time monitoring. However, evaluation stresses existing much more challenging. Currently, relief methods are well-established approach for actual structures. The so-called Drilling method (also known Stress-relief coring technique) one techniques such analysis. For practical use this method, knowledge pivotal factors influence crucial. Therefore, paper presents parametric study performed on one-way post-tensioned slab help understand effect depth core and distance from edge hole (position strain gauges) change vicinity drilled core. Finally, based obtained data, recommendations subsequent experimental program will be summarized. According study, seems that does not significantly main impact attributed hole.
