To calculate dead and live load for industrial steel structures and to apply them using TSD
- Calculate dead load in design report based on IS code and apply dead load on the model
APPICATION OF DEAD LOAD ON THE MODEL.
- Finishes of 50mm
dead load of finishing
0.05*24= 1.2 kn/m2
- Slab as per design
Dead load of slab = 0.15*25= 3.5kn/m^2
- Brickwall 150mm thickness
DEAD LOAD OF BRICK WALL THIICKNESS( 150MM) = 0.15*3*20= 9 KN/M
- Roofing load based on purlin size
DEAD LOAD
- Ceiling loading 0f 0.3KN per sq m
- Calculate live load in design report based on IS code and apply live load on the model
FOR INDUSTRIAL BUIDIN
- Assume the loading based on IS 875
TOILET AND BATHROOM = 2KN/M2
CORRIDOR,PSSAG , STAIRCASE=5KN/M2
KITCHEN = 3N/M2
EQUPMENT ROO= 10KN/M2
- Roof loading
ROOF DEPEND UPON THE ACCESSEBLE AND NON ASSECELE
ACCESS= 1.5 KN/M2
NON ASSECCEBLE = 0.75 KN/M2
- Consider equipment loading as 5KN per sq m
APPICATION OF LIVE LOAD ON THE MODEL.
- Generate a calculation for 5T crane loading based on following inputs
- Centre to Centre of wheel = 10m
- Weight of crab = 40 KN
- Number of wheels = 4
- Wheel base = 2m
ASSUME THE COLUNM DISTANCE BETWEEN GAINTRY RAILS IS = 18 M
LOADING CAPACITY OF CRANE= 50 KN
WEIGHT OF CRAB= 40 KN
MAXIMUM WHEEL LOAD ON THE CRANE =
POINT LOAD ACTING ON THE SPAN DISTANT 1M FROM END = 50 KN
SELF WEEIGT OF CRANE INCLUDING CRAB ACTS UDL ON THE SPAN OF 10 M= 40 /18= 2.23 KN/M
Ra*18= 50*17+4*18*18/2
= 83 KN
Rb= 7.14 kn
take maximum value
Ra= 83 kn
SO LOAD ON EACH OF THE WHEEL= 83/2= 41.5 KN
MAXIMUM BENDING MOMENT DUE TO WHEEL LOAD ON COLUMN OF DISTANCE 10M =
TAKE MOENT ABOUT D
Rc*10= 41.5*6.5+41.5*4.5+2.4*10*5
Rc =57.64 kn
Rd =49.4 kn
bending moent uner whee due to rection RD= 49.4*4.5=222 kn-m
bending moent due to to impact= 0.1* 222= 22.5 kn-m
so total bendig moment = 22.5+222=244.5 kn-m 34.5kn-m
bending moment due to dead load = wl2/2 =2.4*10*5 =120kn-m
maximum bending moment =344.5 kn-m
MAXIMM SHEAR FORCE
FOR MAXIMUMSHEAR FORCE OE O THE WHEEL SOULD BE AT THE SUPPORT
Rc*10= 41.5*10+41.5* (10-2)
=415+332
Rc =74.7 KN
