方钢 F = a 22
圆角方钢 F = a 2-0.8584r23
钢板、扁钢、带钢 F = a 4圆角扁钢 F = a -0.8584r25圆钢、圆盘条、钢丝 F =0.7854d26六角钢 F =0.866a2=2.598s27八角钢 F =0.8284a2=4.8284s28钢管 F =3.1416( D -)9等边角钢 F = d (2b- d )+0.2146( r 2-2q2)10不等边角钢 F = d ( B + b - d )+0.2146( r 2- q 2)11工字钢 F = hd +2t( b - d )+0.8584( r 2- q 2)12槽钢 F = hd +2t( b - d )+0.4292( r 2-q2)
