| 摘 要： | 通过对8根集中荷载作用下高强箍筋T形截面简支梁的试验研究，运用分形理论对试件中斜裂缝的出现、发育及分布特征进行了分析。结果表明：分形理论对斜裂缝自相似性有很好的量化关系。

| Abstract: | In this paper , experimental research on diagonal crack in eight T-shaped simple beams with highstrength stirrup under concentrated load was presented. By using fractal theory, the diagonal crack opening, development and distribution of concrete simple beams with high-strength stirrup under concentrated load is analysed. The results indicate that the fractal theory has a good quantizing relationship on self-similarity of diagonal crack. |
