摘要: 目前，我国正在大力推行装配式建筑，且建筑行业也正在向工业化、低碳化、高性能化转型。陶粒混凝土与普通混凝土(异强混凝土)叠合结构是一些典型装配式结构的局部单元。探究叠合结构剪切性能为大型装配式构件的研究奠定理论基础。然而，异强混凝土叠合结构粘结界面受力机制复杂，界面损伤破坏机理尚不明确。因此，本文开展了基于DIC技术的异强混凝土双面剪切性能研究，探究其不同类型内嵌钢筋桁架的异强混凝土粘结界面的抗剪性能，并建立了抗剪承载力计算模型。同时，为提高模型的适用性，利用现有研究的试验数据验证了模型的可靠度。为我国大型装配式构件的研究应用提供理论依据和技术支撑。
Abstract: At present, China is vigorously promoting prefabricated buildings, and the construction industry is transitioning toward industrialization, low carbon emissions, and high performance. Composite structures composed of ceramsite concrete and ordinary concrete (dissimilar-strength concrete) serve as partial components of typical prefabricated structures. Investigating the shear performance of composite structures can lay a theoretical foundation for the research on large-scale prefabricated members. However, the stress mechanism of the bonding interface in dissimilar-strength concrete composite structures is complex, and the interfacial damage and failure mechanism remains unclear. Therefore, this paper conducts a study on the double shear performance of dissimilar-strength concrete based on Digital Image Correlation (DIC) technology. The shear resistance of bonding interfaces in dissimilar-strength concrete with different types of embedded steel bar trusses is explored, and a calculation model for shear bearing capacity is established. Meanwhile, to improve the applicability of the model, the reliability of the model is verified using experimental data from existing studies. This research provides a theoretical basis and technical support for the research and application of large-scale prefabricated members in China.
