![]() Lap splices are achieved by overlapping this bars over a certain length, thereby enabling this transfer of axial force from the terminating bar into the connecting bar through the mechanism of anchorage (development) bond with the surrounding concrete (As per below fig)Ī) Lap splice action through development bond In this case, the straight length of the lapping bar shall not be less than 15d or 20cm.Īlso, read: What Is Lintel | Type of Lintel Type of Lapping Method: For direct tension, the lap length should be 2 L d or 30d whichever is greater is considered. Generally, development length is 41d where d is the diameter of the bar.
