Question
how the lap length is calculated in reinforcement of 110mm
dia steel of Length 15.00 mtrs. & grade of concrete is M20
 Question Submitted By :: Civil-Engineering
I also faced this Question!!     Answer Posted By  
 
Answer
# 1
I THINK IT IS NOT 110MM IT IS 10MM . FOR SIZE OF ROD THE
LAP LENGTH IS 50 TIMES THE DIAMETER THEREFORE
50X10=500MM.FROM IS 456 200.
 
Is This Answer Correct ?    192 Yes 21 No

Answer
# 2
the rods more than 32mm dia not used for lapping accoding to
is 456 2000 go to the weld only
 
Is This Answer Correct ?    25 Yes 1 No

Answer
# 3
For any dia the lap length should be calculated as per IS:
456 is 50 times the dia of he bar.
 
Is This Answer Correct ?    25 Yes 4 No

Answer
# 4
Lap Length is equal to
50D for Tension zone : 50*10 =500 mm
45D for compression zone : 45*10 =450 mm
 
Is This Answer Correct ?    27 Yes 14 No

Answer
# 5
Lap Legnth is eqal to = (yield stregneth * Dia of stell)/
4* Bond stregnth of Concrete
 
Is This Answer Correct ?    26 Yes 16 No
Jayshankar Dwivedi
 
Answer
# 6
for the compression zone it is 55D & for tension zone it is
45D

i.e for 10mm Dia

Compression---55*10=550mm
Tension-------45*10=450mm
 
Is This Answer Correct ?    48 Yes 39 No

Answer
# 8
Its simple grade of steel X Dia of bar 
Is This Answer Correct ?    8 Yes 4 No
Khuram Shahzad
 
Answer
# 9
if dia is 110 mm then that bar must be welded. bars below 32mm dia
the lap length

In tension 50* dia
In compression 45 * dia
