diameter square of the bar. Divided by 162. gives W/1m length
TMT bar oval weight Stand oval size in mm like 12mm size bar oval size-12*.8=9.6kg/m
Formula for steel bar weight per meter = D2/162 where D is diameter of bar
meaning of 500 D in TMT bar
quenched and self temperedsame as TMT bars
volume of steel multiplied by7850= wt of steel in kgs. Please note that wt of 1 Cum steel is 7850 kg Volume of steel bar can be calculated = cross-sectional area of bar X length cross-sectional area of Bar= pie x d X d/4 (where d is diameter of bar)
Thermo mechanical tempered Reinforcing bar or Structural steel
The modulus of elasticity (E) of TMT (Thermo-Mechanically Treated) bars typically ranges from 200 GPa to 210 GPa (Gigapascals). This property indicates the material's ability to deform elastically when subjected to stress. The precise value can vary slightly depending on the specific grade and manufacturing process of the TMT bar.
Density = mass/volumeThe unit weight of steel is 7850 kg/m3volume of bar = (πd2/4)*Lhence mass = ((πd2/4)*L)*7850= ((3.14 *d2/4)*1)*7850 for unit length= 0.785*d2*7850= 6162.25 d2 if d is in metersor d2 /162 if d is in mm.By putting the value of diameter of rod, you can calculate the unit weight of any size tmt bar.
FS= critical hydraulic gradient/exist hydraulic gradient icr=(saturated unit wt - water unit wt)/water unit wt
0.62 kg/m is the unit weight of 10 mm dia, and you use the thumb rule for all other dia unit weight per metre = d*d/162 where- d is dia of bar/rod in mm
