A lateral-force-resisting system composed of embedded corrugated steel plates and vertical boundary members. It carries load and dissipates energy, adding damping to reduce seismic response.
The corrugated plate forms its own ribs through bending, improving lateral capacity and producing full hysteretic behavior. Compared with ordinary steel plate walls, its energy dissipation can be improved by dozens of times.


Vertical and horizontal corrugated steel walls both provide high bearing capacity and energy dissipation. Steel usage and welding cost can be reduced, and installation is convenient for retrofit and renovation projects.

CSW can be connected on two, three, or four sides. Two-side connection is flexible and easier to coordinate with architectural openings.
Three-side and four-side connections use stiffness from the main structural members to restrain out-of-plane buckling, with higher requirements for construction precision.


Four-side connection embeds the whole wall into the main structure and may omit separate boundary members by using edge plates directly connected to the structure.
