The need of the large structures with more strength and stiffness, but less weight and material is
increasing. To find out such structures, an engineer can design a new structural topology such as a
corrugated-core sandwich plate. A corrugated-core sandwich plate consists of two thin faceplates and
one corrugated sheet which are varied in corrugation pattern. The conventional corrugated-core
sandwich plate is evidently strong in only one direction; it needs to be stiffened in the other direction.
Arranging the corrugated plate in both x- and y-direction is the method to stiff such sandwich plate in
both directions. This paper aims to present the new alternative corrugated-core steel sandwich plate
named the bi-directional corrugated-strip-core steel sandwich plate. The core consists of a series of
corrugated-strip plate which are arranged in both x- and y-direction. This paper also aims to present the
analytical model and to address the efficiency in transverse shear stiffness and strength of this proposed
corrugated-core sandwich plate. According to the preliminary analysis result, the transverse shear
stiffness and strength of this alternative sandwich plate is reasonably increased
