摘要
随着预应力混凝土结构的大量应用,其抗剪性能也备受关注。但对于大部分的试验研究,其纵筋配筋率比实际情况偏高;剪跨比多大于3,对于小剪跨比的梁研究较少。本文利用有限元通用软件ABAQUS独特的功能,建立了简支梁小剪跨比受剪模型,实现了更多细节的模拟,从而使结果更准确可靠,并综合分析其抗剪承载力,得出了一些结论。
Along with the application of prestressed concrete structure, the shear capacity performance has attracted much attention. But most of the experimental study, the ratio of longitudinal reinforcement is higher than the real situation. Shear span ratio is greater than three and the research of small shear span ratio is less. In this paper, using the finite element software-ABAQUS, the small shear span ratio model is established, and more details of the simulation is realized, which make the results more accurate. With the comprehensive analysis of the shear bearing capacity, some conclusions are obtained.
