Abstract: In the study of bending components such as multilayer beams, with a upper and lower layer of steel fiber concrete compared with the normal concrete layer, there will be a sliding process between layers in the process of loading and the sliding between the layers will be different due to depending on the position of the steel fiber concrete layer, thereby the study proposes the suitable position of steel fiber concrete layer to the working process of bending beam so that the sliding between the layers is minimal. In the tension-compression component such as multilayer doubly curved shell roof, the sliding between the layers will depend very much on different boundary conditions such as: the boundary is the joint frame, the boundary is on the single column, rigid constraint, etc. Therefore, in this study, the authors will study the sliding between the layers in 2-layer beams when the steel fiber concrete layer is in upper and lower positions comparing the normal concrete layer and 2-layer doubly curved shell roof with the steel fiber concrete layer under the normal concrete layer with the boundary is rigid constraint by experiment method and ANSYS numerical simulation method to elucidate the sliding ability of the layers during the work of the component.
