Adhesive bonding has recently emerged as an alternative to shear stud connection in steel–concrete composite flexural members. Research on adhesive-bonded steel–concrete composite flexural members is in a preliminary stage, and the behavior of the bond layer in these structures is not well understood yet. A three-dimensional finite element model is developed and used to conduct the parametric investigations. The developed model is validated with experimental results available in the literature. The behavior of the bond layer is defined in terms of normal stress, normal strain, shear stress, and shear strain. Seven different parameters are studied regarding their effect on the behavior of the bond layer. The parameters include load proportion factor, longitudinal distribution of load, transverse distribution of load, width of concrete slab, depth of the concrete slab, Young’s modulus of the adhesive and transverse location of the adhesive fiber. Parametric investigations are carried out to establish the relevance of parameters in terms of their effect on the behavior of the bond layer. The most significant parameters are identified as load proportion factor, longitudinal distribution of load, and Young’s modulus of adhesive.

最近，胶粘结合已成为钢混凝土复合挠曲构件中抗剪栓连接的替代方法。钢骨混凝土复合受弯构件的粘结研究尚处于初步阶段，这些结构中粘结层的行为尚不十分清楚。开发了三维有限元模型，并将其用于进行参数研究。用文献中提供的实验结果验证了开发的模型。根据法向应力，法向应变，剪切应力和剪切应变来定义粘结层的行为。研究了七个不同参数对它们对粘结层行为的影响。参数包括载荷比例因子，载荷的纵向分布，载荷的横向分布，混凝土板的宽度，混凝土板的深度，粘合剂的杨氏模量和粘合剂纤维的横向位置。进行参数研究以建立参数对键合层行为的影响的相关性。最重要的参数确定为载荷比例因子，载荷的纵向分布和胶粘剂的杨氏模量。
