The agriculture facilities are produced with small scale and applied with the use which is various. These facilities are composed of the relatively high-stiffness frame and plate of light stiffness. In the most design of the facilities, we executes about the structural analysis of frame structure. The propose of this study, it is quantified to occurs effect of tension field in plate according to high-stiffness frame. In this study, the finite element analysis for frame structure and boundary element analysis for plate are used.
