柔性纤维与纤维格栅混凝土能量耗散试验比较

Energy Dissipation of Flexible Fiber-and Fiber Grid-Reinforced Concretes

主要从试验的角度分析柔性纤维与纤维格栅混凝土能量耗散的比较。通过静力性能测试和动力性能测试,得到表征试件动力特征的参数。试验结果表明,与柔性纤维混凝土相比,纤维格栅混凝土耗散性能较好,其中5 mm×5 mm系列最好,在混凝土工程中有很好的应用前景。

The energy dissipations of flexible fiber-and fiber grid-reinforced concretes were tested and some parameters signifying the static and dynamic properties of specimens were obtained.The results showed that fiber grid-reinforced concrete has better dissipation properties than flexible fiber-reinforced concrete,among of which 5 mm × 5 mm specimen is the best.
