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

• AIM : To calc502ulate dead load in design report based on IS code and apply the dead load on model

• PROCEDURE :

1. Dead load = 1.2 Kn/M^2
2. Finishes = 500 mm X 24 Kn/m^2 = 1.2 Kn/m^2
3. Brick wall load = 0.15 X 20 X 5.2 = 15.6 Kn/m^2
4. Brick wall load = 0.15 X 20 X 6.8 = 20.5 Kn/m^2
5. Brick wall load = 0.15 X 20 X 14.5 = 14.5 Kn/m^2
6. Roof load = 1.5Kn/m
7. Ceiling load = 0.3 Kn/m

• Open tekla software design software
• Open week 3 file where we have createed a steel structure

• Go to model tab and select slabs on beams option
• Now odd slabs to each other
• Now go to load tab and select load cases and add required load

• Now select load combination and add what required

• Select the level we want to apply loads on
• Select the loads required from the list

• Now go to select the area to apply load on slab

• Go to load tab and select UDL to apply on brick wall
• Apply loads on the roof as well

• AIM : To calculate live load in design report based on IS code and apply live load on the model

• PROCEDURE:

1. Workshop = 5Kn/m^2
2. Staircase = 5 Kn/n^2
3. Corridor = 5 Kn/m^2
4. Meetong room = 5 Kn/m^2
5. Store room = 5Kn/M^2
6. Toilet = 2 Kn/m^2
7. Canteen = 3Kn/m^2
8. Office room = 3Kn/m^2
9. Conference ROom = 5Kn/m^2
10. Equipment room = 10Kn/m^2
11. Rest room = 2 Kn/m^2
12. Administrative room = 5Kn/m^2

Live loads are applied for all the floors as shown below

• Now select the level where we want to apply the loads
• Now select the loads as required at the bottom, left corner

• RESULT :

Calculation of live load in assign report based on IS code and application of live load on the model is done

• AIM : Generate a calculation for 5 T crane loading based on the following inputs

• PROCEDURE :

1. Centre to Centre of wheel =10m
2. Weight of crab = 40 Kn
3. Number of wheel = 4
4. Wheelbase = 2m
5. Crane Capacity = 50 Kn
6. Weight of trolley =10 Kn
7. Hook Approach = 1

Maximum Point load on Crane = Crane capacity + Weight of the trolley

= 50 +10

=60

UDL = Self -Weight of crane distance between grant rails

= 40/14

=2.89 Kn/m

Moment at A :

Ma = 0

Rb = 80 X1 -RbX14 + 2.89X 14 X14/2

Rb = 24.5 Kn

Fy = 0

Ra + Rb - 60 -2.89 X 14 -Rb = 0

Ra = 60 +2.89X14-Rb

Ra = 75.9kN

Assume Self weight of gantry girder = 1.2 Kn/m

Assuming Self weight of gantry girder =0.3 Kn/m

Total self weight = 1.2+0.3

=1.5 Kn/m

Factored Loads =1.5 X1.5

=2.25Kn/m

Now loads on each wheel =37.9 X1.5

= 56.95 KN

= 57 Kn

Moment at c

Mc=0

Rd x 6 = 2.25 x6X6/2 +5.7 X4.5 +57X2.5

Rd = 73.25 Kn

Fy =0

Rc + Rd -57-57-2.25 X6

Rc +Rd =127.5Kn

Rc +Rd =127.5Kn

Rc = -73.25 +127.5

MAX SHEAR FORCE

MF =0

ReX6 - 57-57X4-2.25 X6X6/2=0

Re = 101.75Kn

IMPACT LOAD

= 10% Of wheel load

=0.1 X 101.75

=10.275 KN

V= WI/2

=1.5 X 62

=4.5Kn

Max shear force =4.5 +10.175+101.75

= 116.25 Kn

Lateral load analysis =5% of total weight

=5100 X 60

=3Kn
