1.5.1. 1.5.1. Dead Dead Load Load (D) Conveyor Belt = 30 T, For span = 121 m Calculation Conveyor a meter = 30/121 = 0.2479 T/m Load for each of Truss conveyor system is 0.1240 T/m Chute Load = 0.25 T Conveyor Weight = 5 T Walkway, Platform = 0.25 T/m² x 0.6 m = 0.15 T/m¹ 1.5.2. 1.5.2. Live Live Load Load (L) Coal Bulk Density = 0.9 T/m³, Load Effective Area = 0.178 m², Speed Max =
3 m/s, Load by Hours 1922 T/H, and of The Load of Coal by meter is 0.17796 T/m and 0.0890 T/m for each of truss conveyor system. Human Load = 0.1 T/m² x 0.6 m= 0.06 T/m¹ 1.5.3. Equipment Load (Q) Equipment Loads refer to mechanical drawings 1.5.4. Wind Load (W) Wind pressure 40 kg/m² = 0.04 T/m² . 1.5.5. Earthquake Load (E) Nominal shear load of static equivalent V can calculated by: V= C1.I.Wt/R C1
= 0.50 (Zone 2 with soft base soil)
I
= 1.5
R
= 4.5
Wt = Weigth of structure = D + L + ½ Q Load distribution over the height of structure :
Wi = portion of W at level -i zi = height above the base to level -i 1.5.6. Rain Load (H) H = 40 – 0.8α = 34.4 kg/m² = 0.0344 kg/m²(α = 7°) 1.5.7. Loading Combination Based of AISC-LRFD 93 ( SNI 03-1729-2002), Load combination for steel is : ▪
U = 1,4D
▪
U = 1,2D + 1,6L + 0.5(Q atau H)
▪
U = 1,2D + 1,6(Q or H) + (ϒ LL or 0.8W)
▪
U = 1,2D + 1,3W + ϒ LL + 0.5(Q or H)
▪
U = 1,2D ± 1,0E + ϒ LL
▪
U = 0,9D ± ( 1,3W or 1,0E) where
ϒ L
= 0.5 (L < 0.5 T/m²) or
ϒ L
= 1.0 (L ≥ 0.5 T/m²)
