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(jié)果表明,在鋼梁截面大小相同的條件下,樓板位于鋼梁下翼緣的組合梁和樓板位于鋼梁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 ,樓板位于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 。
