Rebartus lej suav lej

Formula: txoj kab uas hla mm × txoj kab uas hla mm × 0.00617 × ntev m

Piv txwv li: Rebar Φ20mm (inch) × 12m (ntev)

Luas : 20 × 20 × 0.00617 × 12 = 29.616kg

 

Cov yeeb nkab steelluj formula

Formula: (sab nraud txoj kab uas hla - phab ntsa thickness) × phab ntsa thickness mm × 0.02466 × ntev m

Piv txwv li: steel yeeb nkab 114mm (sab nraud txoj kab uas hla) × 4mm (phab ntsa thickness) × 6m (ntev)

Kev suav: (114-4) × 4 × 0.02466 × 6 = 65.102kg

 

Pav ca hlauluj formula

Formula: sab dav (mm) × thickness (mm) × ntev (m) × 0.00785

Piv txwv: ca steel 50mm (sab dav) × 5.0mm (thickness) × 6m (ntev)

50 × 5 × 6 × 0.00785 = 11.7.75 (kg)

 

Hlau phajtus lej suav lej

Formula: 7.85 × ntev (m) × dav (m) × thickness (mm)

Piv txwv li: steel phaj 6m (ntev) × 1.51m (dav) × 9.75mm (thickness)

Kev suav: 7.85 × 6 × 1.51 × 9.75 = 693.43kg

 

Sib npaugkaum steelluj formula

Formula: sab dav mm × thickness × 0.015 × ntev m (nrawm xam)

Piv txwv li: Lub kaum sab xis 50mm × 50mm × 5 tuab × 6m (ntev)

Kev suav: 50 × 5 × 0.015 × 6 = 22.5kg (lub rooj rau 22.62)

 

Lub kaum sab xis hlau tsis sib xws luj formula

Formula: (sab dav + sab dav) × tuab × 0.0076 × ntev m (nrawm xam)

Piv txwv li: Lub kaum sab xis 100mm × 80mm × 8 tuab × 6m (ntev)

Kev suav: (100 + 80) × 8 × 0.0076 × 6 = 65.67kg (Table 65.676)
