What is the lap length of steel in tension zone & compression zone

Question

Accepted Answer

Lap length of steel in tension zone is 50 times the diameter of the bar, while in compression zone it is 40 times.

Lap length is the length of overlap between two bars in a reinforced concrete structure.
In tension zone, the lap length is longer to ensure proper transfer of stress from one bar to another.
In compression zone, the lap length is shorter as the bars are not subjected to as much stress.
For example, if the diameter of the bar is 10mm, the lap length in tension zone would be 500mm and in compression zone it would be 400mm.

Accepted Answer

Lap length of steel in tension zone is 50 times the diameter of the bar, while in compression zone it is 40 times.

Accepted Answer

Lap length of steel is 30D in tension zone and 24D in compression zone

Accepted Answer

40d and 50d tension and compress

Accepted Answer

30d in tension 40d in compression

Accepted Answer

30D for tension and minimum 24d for compression.

Accepted Answer

45×d and 50×d is tenssion and compression zone
