其中1.06為鍍鋅層系數(shù)。 </p> <p> 六、怎么算方矩管的支重以及每支管的單價(jià)？ </p> <p> 《四個(gè)面的寬度相加（周長）/3.14-壁厚》*壁厚*0.02466*米數(shù)=單支方矩管重量 </p> <p> 每噸的單價(jià)*支重=每只方矩管的單價(jià) </p> <p> 要是檢尺賣例如實(shí)際是2.75的要按3.0的檢尺賣就用單價(jià)/3.0*2.75*單支方矩管重量就可以了。二、方矩形鋼管的豎向承載力計(jì)算方法 1.計(jì)算壓應(yīng)力，就是豎向壓力作用在方矩形鋼管的橫截面上所產(chǎn)生的壓應(yīng)力。這個(gè)比較簡單，就是壓力（單位N）除以方矩形鋼管橫截面面積（單位m平方）。只要壓應(yīng)力小于材料的許用應(yīng)力即可。 </p> <p> 2.方矩形鋼管受壓，要計(jì)算穩(wěn)定性。穩(wěn)定性的計(jì)算較為復(fù)雜。要看連接的方式是兩端固接還是一端固接另一端鉸接。估計(jì)你不只使用1跟立柱，所以可以簡單計(jì)算成兩端固接。臨界壓力簡單計(jì)算：P=(4*n*Pi^2*E*I)/[(L/2)^2]。n立柱的數(shù)量，pi^2就是拍的2次方，E彈性模量，I慣性矩，L立柱長度。 </p> <p>
