This paper presents the basic data for the strength behavior of longitudinally profiled plates(LP plate). The effects of loading conditions, thickness and slenderness ratio of plates are examined by using FEM analysis. The analysis results shown that the strength behavior of LP plate is varied with the loading conditions. The major causes of the reduction in strength are the distribution of deflection and the slenderness ratio of plate. Based on the results, this paper presents some discussions about the strength evaluation of LP plate with considering the equivalent thickness.
