(煤炭工業(yè)部太原設(shè)計研究院 030001)[提要] 對桿件穩(wěn)定計算中的兩個重要因素——桿件計算長度和容許長細(xì)比進行分析研究,提出桿件計算長度的近似計算方法,并給出網(wǎng)殼結(jié)構(gòu)桿件在殼體曲面內(nèi)及曲面法線方向的計算長度系數(shù)的取值和容許長細(xì)比數(shù)值,供設(shè)計人員采用。
[關(guān)鍵詞] 網(wǎng)殼 桿件穩(wěn)定 計算長度 容許長細(xì)比The determining methods of steel latticed shells member's calculated length in internal and normal direction of curved surface are developed, and the value of calculated length of members and the slenderness ratio are given also. The results can be referred in engineering practice.
Keywords: steel latticed shells; calculated length of member; slenderness ratio; stability analysis
