lower elastic limit 中文意思是什麼
lower elastic limit
解釋
彈性下限-
Elastic theory and plastic theory are adopted in the analysis of the two section composite beam. elastic theory suggests, on the condition of the same steel beam section size, the composite beam for the floorslab is suited lower flanges convertion section stiffness cuts down by 75. 1 %, elastic limit bending resistant capability cuts down by 47. 9 %, than the composite beam for the floorslab is suited on the top flange. it s conversion section stiffness is lifted 8. 0 %, elastic limit bending resistant capability is lifted 0. 20 %, than the steel beam
彈性理論分析的結果表明,在鋼梁截面大小相同的條件下,樓板位於鋼梁下翼緣的組合梁和樓板位於鋼樑上翼緣的組合梁相比,其換算截面剛度降低75 . 1 ,梁的彈性極限抗彎承載力降低47 . 9 ,樓板位於鋼梁下翼緣的組合梁和純鋼梁相比,其換算截面剛度提高8 . 0 ,梁的彈性極限抗彎承載力提高0 . 2 。
