It is important to clarify the stress transfer mechanism through the contact surface between steel and concrete in steel-concrete hybrid structures. Then, we carry out the static test of the specimen which is composed of the steel plate and two concrete blocks, and investigate the bonding behavior of the contact surface under the bearing force. In this case, two different ways of applying the bearing force are examined.The main conclusions of this research may be summarized as follows :1.When the contact surface between steel and concrete is subjected to the shear force under the constant bearing force, the relative displacement between the steel plate and the concrete block is very small up to reaching the maximum shear force. But, the shear force significantly decreases with the increase of the displacement beyond the maximum shear force and then the shear force tends to approach a constant residual one.2.The relation between the maximum shear stress and the bearing force, and the relation between the residual shear stress and the bearing stress show almost linear relations.3.The relation between the maximum shear stress and the bearing stress as well as the relation between the shear stress and the slip does not depend on the application method of the bearing employed here.

阐明钢-混凝土混合结构中钢与混凝土接触面的应力传递机制具有重要意义。然后，对钢板和两块混凝土块组成的试件进行静力试验，研究接触面在承载力作用下的粘结行为。在这种情况下，研究了两种不同的施加承载力的方式。本研究的主要结论可概括如下：1.当钢材和混凝土的接触面在恒定的承载力下受到剪力时，钢板和混凝土块之间的相对位移很小，直至达到最大剪力。但是，超过最大剪力后，随着位移的增加，剪力显着减小，然后剪力趋于接近恒定的残余剪力。2.最大剪应力与承载力之间的关系，以及残余剪应力与承载应力之间的关系几乎呈线性关系。3.最大剪应力与承载应力之间的关系以及剪应力与滑移之间的关系不依赖于应用方法。 这里使用的轴承。
