Feel Free Creation's Rebar detail

 Lap Table as per BS 8110-1:1997 Minimum laps:  The minimum lap length to be ≥ 15Ø or 300mm and for fabric reinforcement ≥ 250mm.  Design of tension laps: The length should be at least equal to the design tension anchorage length necessary to develop the required stress in the reinforcement. Lap lengths for unequal bar Ø may be based upon the smaller bar Ø The following provisions also apply:  a) where a lap occurs at the top of a section as cast and the minimum cover < 2Ø, the lap length to be increased by a factor of 1.4;  b) where a lap occurs at the corner of a section and the minimum cover to either face < 2Ø or, where the clear distance between adjacent laps < 75 mm or 6Ø, the lap length to be increased by a factor of 1.4;  c) in cases where both conditions a) and b) apply, the lap length to be increased by a factor of 2.0.  Design of compression laps:  The length to be ≥ 1.25 x compression anchorage length. Lap lengths for unequal ...

 General Standards for UK Detailing 1. All reinforcement details (such as minimum diameter and minimum or maximum spacing) are only for comparison purpose to raise RFI if the design intent does not meet the requirement. Any changes or addition or omission to design intent based on standard practice or for flexibility or for consistency or for simplified/rationalized method of detailing must be confirmed with client prior to detailing.  2. Detailing standards to be checked with client whether the design is based on BS or EC2 prior to detailing.  3. Cover to reinforcement to be cross checked against nominal cover specified for each case (i.e Internal, External, Earth face etc.)  a. If given cover < nominal cover, adequate tolerance (refer Table) to be adapted and the same to be confirmed with client.  b. If given cover ≥ nominal cover, additional tolerance to be ignored and the same to be confirmed with client.  c. Minimum cover to be 25mm (or main bar Ø) ...
