style="text-indent:25px">波形鋼腹板PC組合箱梁橋是20世紀(jì)80年代早期出現(xiàn)的一種新型組合結(jié)構(gòu)橋梁,具有自重輕,預(yù)應(yīng)力效率高,施工周期短,造型美觀等諸多優(yōu)點(diǎn);同時(shí),其獨(dú)特的結(jié)構(gòu)形式使結(jié)構(gòu)各組成部分受力明確.波形鋼腹板PC組合箱梁橋在法國(guó),日本等國(guó)家得到了較較廣的研究和應(yīng)用,目前,波形鋼腹板PC組合箱梁橋在我國(guó)同樣展現(xiàn)出蓬勃的發(fā)展前景,其應(yīng)用范圍正逐步向變截面大跨度梁橋擴(kuò)展,結(jié)構(gòu)更加復(fù)雜. 現(xiàn)有研究主要集中在波形鋼腹板的剪切屈曲和抗彎,抗扭以及截面承載力等工作性能上,包括縮尺模型試驗(yàn)和有限元數(shù)值分析也多是集中于波紋板梁或該類組合結(jié)構(gòu)簡(jiǎn)支梁的受力性能,而對(duì)該結(jié)構(gòu)在大跨度連續(xù)箱梁的靜力分析和動(dòng)力特性研究較少。采用鋼板箱梁是由于它具有很大的抗扭剛度。北京疊合梁設(shè)計(jì)深化價(jià)格</p><p

style="text-indent:25px">鋼板箱形梁與傳統(tǒng)混凝土箱梁橋相比,波形鋼腹板組合箱梁橋由于上部結(jié)構(gòu)自重減輕,但剛度幾乎沒有減少,故而其自振頻率略有增大,但地震作用下各橋墩的彎矩和軸力均有較大幅度的減小,結(jié)構(gòu)抗震能力明顯提高;表明波形鋼腹板組合箱梁的抗震性能要明顯優(yōu)于傳統(tǒng)混凝土箱梁,是值得在我國(guó)西部高烈度山區(qū)推廣的一種較合理的橋型方案。箱型梁由于用途的特殊性，箱型梁作用很大，所以在生產(chǎn)加工時(shí)必須嚴(yán)格保證質(zhì)量。箱型梁生產(chǎn)加工廠家在新源物資交易市場(chǎng)比較多，具體可以實(shí)際考察。深圳鋼箱梁實(shí)用設(shè)計(jì)哪家好</p><p
