| 要旨 | In this paper, the 3-D size effect was studied based on the analysis of torsion strength of concrete beams. It is shown that the fictitious crack approach can be extended with three orthogonal rod elements, which can successfully predict the size effect on the torsion strength of concrete. The numerical investigation has been carried out by simulation using the program ANACS of three dimensional version. To judge the validity of the results, these were compared with Bazant's size effect law. |
