Comparative research on method to calculate overall stability of full - web type axially compressed member 鋼結構實腹式軸壓構件整體穩(wěn)定性計算方法的比較研究
In active code for design of steel structures , axially compressed members are calculated not as torsional - flexural buckling but as flexural buckling with equivalent slenderness ratio , residual stress and initial geometry imperfection are also taken into account as flexural buckling 我國現(xiàn)行鋼結構設計規(guī)范( gb50017 )采用換算長細比的方法將彎扭失穩(wěn)等效為彎曲失穩(wěn),其殘余應力和初始幾何缺陷均按彎曲失穩(wěn)考慮。
Then according to the compare and analysis of simulative results , theory calculation and testing data , the feasibility of simulating the axis compressed member is verified by the finite element method . it can be extended to the finite element simulation of the member under eccentricity compression 通過對計算結果與理論計算值、實驗測試數(shù)據的比較分析,驗證了應用有限元法模擬軸心受壓構件的可行性,并將其推廣到偏心受壓構件的有限元模擬中。
