The present paper demonstrates and discusses a potential of steel latticed plates to use as seismic walls, through experimental study. Cyclic shear load tests of five steel latticed plates, composed of equilateral triangular grids, were conducted to investigate buckling and post-buckling strength and ductility. Three of five plates yield out-of-plane overall buckling and the rest in-plane member buckling as predicted. The buckling and post-buckling strengths can be approximated using the generalized slenderness calculated by linear buckling analysis and its function for inelastic strength, regardless to the buckling mode. Moreover, these latticed plates show good ductility and energy dissipation capacity. But a disadvantage that the buckling deformation is too observable is also exposed.
