style="text-indent:25px">為了克服純GFRP箱梁剛度低,抗剪能力弱,脆性破壞和初期造價高等缺點,結(jié)合鋼材剛度大,抗剪能力強,延性好和價格低等優(yōu)點,提出了一種新型GFRP/鋼復(fù)合箱梁.以某一特定GFRP箱梁為例,通過理論計算,分別考察了在GFRP箱梁上下翼緣,腹板和全截面中復(fù)合鋼板后鋼板體積比(復(fù)合部位鋼板體積與總體積之比)對GFRP箱梁性能的影響,同時對比分析了在GFRP箱梁上下翼緣中復(fù)合單向CFRP的情況.分析結(jié)果表明:復(fù)合鋼板后,GFRP箱梁的性能得到了大幅提升,總造價卻幾乎保持不變,同時全截面復(fù)合鋼板的性能明顯優(yōu)于上下翼緣復(fù)合鋼板的。箱形梁不會**建筑高度或者滿足建筑高度而增加建筑層高帶來的造價提高的弊端。</p><div
