摘要
对目前混凝土动荷载的试验方法与特性进行了综述介绍,分析了动荷载的分类、常用的试验方法及设备仪器,从循环荷载下和冲击荷载下两方面阐述混凝土的疲劳性能和动态性能研究成果,最后总结提高混凝土动力性能的改善措施,为以后的研究提供参考。
This paper reviews test methods and characteristics of concrete dynamic load, and analyzes classification of such load, normal test methods and conventional test instruments. It further elaborates research findings on concrete＇s fatigue property and dynamic property in terms of cyclic loading and impact loading, and proposes measures for improving concrete＇s dynamic property that may serve studies in the future.
