What is the lap length of bars for compperision zone

Question

Accepted Answer

The lap length of bars for compression zone is the minimum length required to ensure proper transfer of stress between two overlapping bars.

The lap length is determined based on the diameter of the bars, concrete strength, and the bond strength between the bars and concrete.
It is important to provide adequate lap length to prevent failure due to inadequate bond between the bars and concrete.
The lap length for compression zone is generally shorter than that for tension zone.
The lap length can be calculated using empirical formulas or specified in design codes and standards.
For example, as per ACI 318, the minimum lap length for compression zone is 30 times the diameter of the bar.
