| 摘 要： | 研究了废旧轮胎橡胶粉混凝土简支梁和普通混凝土梁在静力荷载作用下的裂缝的产生发展、应变以及挠度等变化，研究结果表明：橡胶颗粒的掺入使得混凝土简支梁在相同静力加载状态下比普通混凝土构件裂缝出现晚，发展缓慢，相同条件下弹性应变和挠度大于普通混凝土梁，橡胶颗粒的掺加提高了混凝土梁的韧性。 |
| 关 键 词： | 废旧轮胎 橡胶粉 混凝土简支梁 裂缝 应变 |

| Abstract: | In this paper the changes of crack under static load affect development, strain and deflection etc. In rubber powder concrete simply supported beam and average concrete beam have been researched. The result indicated that in rubber powder concrete simply-supported beam crack appears should be latter than average concrete simply-supported beam under identical loading load with circumstances. Its development, elasticity strain and deflection were greater than average concrete simply-supported beam, rubber power adulterating having raised the toughness of concrete simply-supported beam. |
| Keywords: | waste tire rubber power concrete simply-supported beam crack strain |
