由于剪切破坏的复杂性和重要性,许多学者对此问题从各方面进行了研究。根据国内外已有的钢筋混凝土梁抗剪性能研究成果,系统地阐述了各种抗剪承载力的计算模型及基本原理,评述了各模型间的内在联系及适用性;指出了各种研究方法及模型的优缺点;探讨了该领域的研究发展趋势,并对未来的研究工作提出了建议。研究表明:现有抗剪理论存在各自的局限性,正确认识其特点才可合理运用于不同结构形式的抗剪性能分析。
Due to the complexity and importance of shear damage, many scholars have studied this issue from various aspects. According to the research results of the shear properties of the existing reinforced concrete beams both at home and abroad, the calculation models and basic principles of various kinds of shear capacity are expounded systematically, and the intrinsic relations and applicability of the models are reviewed. Various research methods And the advantages and disadvantages of the model; discusses the research trends in this field, and puts forward suggestions for future research work. The research shows that the existing shear theory has its own limitations, and its characteristics can be properly applied to the analysis of shear resistance of different structures.
