Effect of Treshold Values on Prediction of Natural Vibration Properties of Concrete Sample

Abdulkerim Ergut, Sergen Aksay, Gokhan Altintas


In this study, firstly, three different samples of concrete material were obtained with computer aided imaging techniques. The sampled images were transformed into three-dimensional models that consisted of pixels. The threshold and flodfill algorithms have been used to transform the samples into three dimensions in the computer environment. The ABAQUS® package program, which is computer aided engineering software (CAE), was used to perform analyzes of solid element samples. Considering the available data and analysis, the change of the determined threshold ranges were observed with the help of imaging techniques. Also, changes in the natural frequency values obtained by the modes of the total number of points, volume, number of elements, and modes of the elements were observed.Before start the analysis, when threshold obtained it’s changing, threshold must obtain sensitively. It makes inference.
