- 109 Crack Generating Detection Technique of Reinforced Concrete Structure Using Three-Dimensional Measurement Based on Stereo Camera System
抄録
It is extremely important to measure the strain distribution of reinforced concrete structures and to detect the generated cracks location. Currently, the digital image correlation (DIC) method is applied for measuring technique. However, the DIC method has several problems concerning accuracy; an out-of-plane deformation of structures has an adverse effect on the strain measurement accuracy. For improving the strain measurement accuracy of the DIC method, it is essential to compensate the equivalent strain owing to the out-of-plane deformation of the measurement objects. Therefore, it is necessary to measure the three-dimensional surface geometrization using the stereo camera system. This paper discusses the crack generating detection technique of reinforced concrete structure using the three-dimensional method measurement based on the stereo camera system. In particular, the previously our proposed compensation method for the equivalent strain is used. As a result, it is found that the three-dimensional measurement method based on stereo camera system with our compensation method is superior to existing both the strain distribution and the crack generating detection technique, on a basis of a series of experimental examination using the large-scale four-point bending test.
