To calculate dead and live load for industrial steel structures and to apply them using TSD

1.

Given,

• Dead load = 1.2 KN/m^2
• Finishes = 0.05 * 24 =1.2 KN/m^2
• Brickwall load

1. Ground to intermediate = 0.15*20*5.2 = 15.6 KN/m^2
2. Intermediate to roof = 0.15*20*6.8 = 20.4 KN/m^2
3. Roof to top most floor= 0.15*20*4.8 = 14.4 KN/m^2

• Ceiling load= 0.3 KN/m^2
• Roof load = 1.5 KN/m^2

Procedure:

• Open TEKLA and now we need to add different loads in load cases tab
• 
• Now add the load combinations and add the finishes loads to the levels
• 
• Now add the Brickwall loads , ceiling loads and roof loads

2.

From IS 875, we take the live loads as for as,

• Workshop, Staircase,Administration room, Store room, meeting room, conference room, corridor= 5KN/m^2
• Toilet, Rest Room = 2KN/m^2
• Canteen, Office room = 3KN/m^2
• Equipment room = 10 KN/m^2

• Now we need to apply the live loads for the floors
• 

3.

Given,

• Centre to centre span of the wheel = 10m
• Weight of the crab = 40 KN
• Number of wheels = 4
• Wheel base = 2m
• Crane capacity= 50 KN
• Weight of trolley = 10KN
• Minimum hook approach = 1m
• Maximum point load on crane = crane capacity+ weight of trolley = 60KN
• UDL = Self weight of crane / distance between rails = 2.89 KN/m

• Moment at A

'Sigma'Ma = 0

60*1-Rb*14 +2.89*14/2 = 0

Rb= 24.5 KN

'Sigma' Fy = 0

Ra+Rb -60-2.89*14 = 0

Ra = 75.9 KN

Now lets assume the total self weight of the grider = 1.5 KN/m

Factored load = 1.5 *1.5 = 2.25 KN/m

Load on each wheel = 75.9/2 =37.97 KN

Factored load= 37.97 *1.5 = 57 KN

• Moment at C

'Sigma'Mc=0

Rd*6 = 2.25*6*3+57*4.5+57*2.5

Rd=73.25 KN

'Sigma' Fy = 0

Rc+Rd-57-57-2.25*6

Rc=54.25 KN

'Sigma' Mf=0

Re*6-57*6-57*4-2.25*6*3 = 0

Re = 101.75 KN

V= Wl/2 = 1.5*6 /2 =4.5 KN

Impact load = 10% of wheel load = 10 % * 101.75 = 10.175 KN

Maximum shear force = 10.175 + 101.75 + 4.5 = 116.425 KN

Lateral load analysis = 5% of total weight = 3 KN
