This research is about design of slit type FLD which secure the buckling stability of compressive brace. 4 slit type and 8 slit type specimens were experimented by pure compressive loading. Comparing the experiment results with FEA results, the good correspondence is appeared each other. Also for deriving strength-displacement formular, an unit section of slit type FLD is transferred to idealized sandwich section. This formular explains satisfactorily experiment results, in given condition. The result of this research will be used as basic data in FLD design.
