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

1.Aim: To Calculate dead load in design report based on IS code and apply dead load on the model

Procedure:
Load calculations:
• Dead Load=1.2 kn/m^2

• Finishes=500mmx24 kn/m^3 = 1.2 kn/m^2

•Brick wall load =0.15x20x5.2=15.6 kn/m^2 (Ground to intermediate floor)

• Brick wall load =0.15x20x6.8=20.5 kn/m^2(intermediate floor to Roof)

• Brick wall load =0.15x20x4.8=14.5 kn/m^2(Roof to top floor)

• Roof load =1.5 kn/m

• ceiling load=0.3 kn/m

now open tekla structural designer software

• Open the week 3 file where we have created a steel structure

•  Now we have week 3 file below

• Now go-to model tab and select slabs on beams option as shown

• Now add slabs to each floor as shown

• Now go to the load tab and select load cases

• Now we get a window named as loading as shown

• Now add required loads in this window

• Now Goto load tab and select combinations

• Now we get a window named as loading as shown

• Now click on combinations and add required combinations 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

• Now go to the load tab and select the apply load on the slab

• Now we can see Area load to apply load on the slab

• Now select the level where we want to apply the loads

• Now select the loads as required at the bottom left corner

• Now go to the load tab and select the UDL to apply load on the brick wall

• Now we can see the UDL applied on the brick wall

• Finally, apply loads on the Roof

Result: Calculation of dead load in design report based on IS code and application of dead load on the model is done.

2. Aim: To Calculate live load in design report based on IS code and apply live load on the model

Procedure:
Based on the IS 875 the live loads are applied, as follows.

• Workshop = 5 kn/m^2

• Staircase =5 kn/m^2

• Corridor = 5 kn/m^2

• Meeting Room = 5 kn/m^2

• Store Room =5 kn/m^2

• Toilet = 2 kn/m^2

• Canteen = 3 kn/m^2

• Office Room = 3 kn/m^2

• Conference room = 5 kn/m^2

• Equipment Room = 10 kn/m^2

• Rest Room = 2 kn/m^2

• Administration Room = 5 kn/m^2

The 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

• Now go to the load tab and select the Area to apply load on the slab

• Now we can see the Area load applied on the slab

Result: Calculation of live load in design report based on IS code and application of live load on the model is done.

3 Aim: Generate a calculation for 5T crane loading based on the following inputs

Procedure:
Given Data:
• Centre to Centre of wheel = 10 m

• Weight of crab = 40 KN

• Number of wheels = 4

• Wheelbase = 2 m

• Crane Capacity=50 KN

• weight of trolley = 10KN

• hook approach = 1m

Maximum point load on Crane=Crane capacity + weight of the trolley
=50+10
=60 KN

UDL= self weight frame distance/ls
=40/14 =2.89KN/m
Moment at A:

`summ`MA=0
=60xl-RBX14+2.89X14X14/2
RB=24.5KN

`summ`Fy=0 RA+RB-60-2.89X14=0
RA=60+2.89X14-RB
RA=75.9KN

Now assuming self weight of gantry grider=1.2 kN/m

assuming self weight of gantry grider=0.3KN/m

Total self weight=1.2+0.3 =1.5KN/m

FACTORED LOAD=1.5x1.5 =2.25KN/m Now load on each wheel=75.9/2 =37.97KN

Factored load=37.97x1.5 =56.95KN
=57KN

Moment at C:

`summ`Mc=0

RDX6=2.25x6x6/2+57x4.5+57x2.5 RD=73.25KN

`summ`Fy=0 RC+RD-57-57-2.25X6 RC+RD=127.5KN

RC+73.25=127.5
RC=127.5-73.25
RC=54.25KN
MAX SHEAR FORCE

`summ`MF=0

REX6-57-57X4-2.25X6X6/2=0

RE=101.75KN

IMPACT LOAD:
=10% OF WHEEL LOAD
=0.1X101.75
=10.175KN

V=WI/2 = 1.5X6/2
=4.5KN

Max shear force=4.5+10.175+101.75 =116.425KN
Lateral load analysis=5% of total weight

(5/100)x60
=3KN
