H型鋼是一種新型經(jīng)濟建筑用鋼。其實H型鋼與其相似的還有工字鋼，諸暨矩形方管規(guī)格，H型鋼軋制時截面上各點延伸較均勻、內(nèi)應(yīng)力小，與普通工字鋼比較，具有截面模數(shù)大、重量輕、節(jié)省金屬的優(yōu)點，可使建筑結(jié)構(gòu)減輕30-40%；又因其腿內(nèi)外側(cè)平行，腿端是直角，拼裝組合成構(gòu)件，諸暨矩形方管規(guī)格，可節(jié)約焊接，諸暨矩形方管規(guī)格、鉚接工作量達25%。常用于要求承截能力大，截面穩(wěn)定性好的大型建筑。HN是H型鋼高度和翼緣寬度比例大于等于2，主要用于梁。諸暨矩形方管規(guī)格</p><div

1、冷軋成型H型鋼允許截面出現(xiàn)局部屈曲，從而可以充分利用桿件屈曲后的承載力；而熱軋型H型鋼不允許截面發(fā)生局部屈曲。 2、熱軋型H型鋼和冷軋型H型鋼殘余應(yīng)力產(chǎn)生的原因不同，所以截面上的分布也有很大差異。冷彎薄壁型鋼截面上的殘余應(yīng)力分布是彎曲型的，而熱扎型鋼或焊接型鋼截面上殘余應(yīng)力分布是薄膜型。 3、熱軋型H型鋼的自由扭轉(zhuǎn)剛度比冷軋型H型鋼高，所以熱軋型鋼的抗扭性能要優(yōu)于冷軋型H型鋼。冷彎薄壁型H型鋼中帶卷邊的是型鋼邊緣設(shè)有加強肋，不帶卷邊的型鋼邊緣沒有加強肋。諸暨矩形方管規(guī)格</p><p
