To provide a plate frame structure design system, a plate frame structure design method, and a plate frame structure design program capable of designing a plate frame structure member which is lighter while satisfying design requirements.SOLUTION: A plate frame structure design system comprises: a parameter value setting unit that sets a plurality of parameter values for a predetermined design parameter in a plate frame structure member 2; an analysis unit that performs a linear finite element analysis for an analysis model of the plate frame structure member 2 using each of the plurality of parameter values, and calculates at least one of buckling occurrence load and buckling collapse load in the analyzed plate frame structure member 2 and the weight of the plate frame structure member 2; and a calculating unit that calculates the load state in a structure having the plate frame structure member 2, and calculates the parameter value of the design parameter of the plate frame structure member 2, which satisfies a predetermined design requirement for the structure and the weight of which is equal to or less than a predetermined weight threshold, using information based on the analysis result by the analysis unit.SELECTED DRAWING: Figure 2

    【課題】設計要求を満たした上でより軽量な板骨構造部材を設計することのできる板骨構造設計システム、板骨構造設計方法、及び板骨構造設計プログラムを提供することを目的とする。【解決手段】板骨構造設計システムは、板骨構造部材2における所定の設計パラメータに対して、複数通りのパラメータ値を設定するパラメータ値設定部と、複数通りのパラメータ値のそれぞれを用いて、板骨構造部材2の解析モデルに対して線形有限要素解析を行い、解析した板骨構造部材2における座屈発生荷重及び座屈崩壊荷重の少なくともいずれか一方と、板骨構造部材2の重量とを演算する解析部と、板骨構造部材2を有する構造体における荷重状態を演算し、解析部における解析結果に基づく情報を用いて、構造体の所定の設計要求を満たし、かつ重量が所定の重量閾値以下となる板骨構造部材2の設計パラメータのパラメータ値を演算する演算部とを備える。【選択図】図2
