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、发育以及分布特征进行分析.结果表明:分形理论对斜裂缝自相似性有很好的量化关系.In this paper, experimental research on diagonal crack of eight T-shape simple beams with high-strength stirrup under concentrated load was presented. By using fractal theory, the diagonal crack opening, development and distributing of concrete simple beams with high-strength stirrup under concentrated load is analysed. The results indicate that the fractal theory have good defmite relationship on self-similarity of diagonal crack.
