本文根据大连理工大学开展的不同类型混凝土双轴压强度性能的试验资料,并结合其他研究者的研究资料,对混凝土在双轴压荷载作用下的破坏模式、双轴压强度进行了分析总结。同时从材料构成上对双轴压强度相对于单轴压强度提高的程度进行了分析,对各种混凝土的双轴压强度破坏准则进行了描述。希望本文内容为今后进一步开展混凝土多轴试验和有关设计规范考虑混凝土的多轴强度和非线性分析提供依据。
Based on the experimental data of the biaxial compressive strength of different types of concrete carried out by Dalian University of Technology and the research data of other researchers, the failure mode and the biaxial compressive strength of the concrete under the biaxial compressive load were analyzed and summarized. At the same time, the degree of biaxial compressive strength with respect to uniaxial compressive strength was analyzed from the material composition. The failure criterion of biaxial compressive strength of various concrete was described. It is hoped that the content of this article will provide the basis for further carrying out multi-axial concrete test and relevant design specifications considering the multi-axial strength and nonlinear analysis of concrete.
