This paper deals with proposals and experimental results on evaluation methods of flexural behaviors out of plane concerning about panel components for dry renewals of external walls. For utilizing various kinds of advanced materials, a new scale of flexural bearing capacity, namely effective first cracked flexural strength is proposed by considering ductility. GRC,aluminum, inorganic extruded materials and many kinds of hybrids, such asmetal-ceramics were experimentally examined to comply with a criterion of more than 7 MPa in the specific flexural strength presumed herein. Furthermore, relationships between flexural moment and curvature is proposed for designing the panels against various kinds of external forces.
