| 摘 要： | 按照地震荷载作用的速率范围，利用最新研制和改造的大型混凝土静，动试验系统，进行了4种数量级加载速率下混凝土轴向压缩试验，测得了混凝土动态强度，弹性模量，泊松比及应力-应变关系，根据加载条件和混凝土静，动态试验结果间的关系，建立了混凝土的动态本构模型，为地震区的混凝土结构，海上混凝土采油平台和核防御壳等结构受动荷载作用的分析提供参考。

Dynamic compressive test of concrete and its constitutive model |
| |
| Abstract: | According to the magnitude of the loading rate expected for earthquake cases, the concrete compressive tests under four orders of loading rates are completed with the galleon concrete static and dynamic test system which is rebuilt recently in the State Key Laboratory of Coast and Offshore Engineering in Dalian University of Technology. The dynamic strength, elastic modulus, Poisson' ratio of concrete are measured in the test, and the stress strain cure is obtained. The dynamic constitutive model of concrete is established based on the loading condition and the results of the test. The study results make a reliable foundation for the dynamic analysis of concrete structures, such as structures within earthquake regions, concrete oil platforms, defense shucks, which are subjected to impact compression. |
