@kHURRAM ALImakes a good point about staggered laps. Staggered laps are a good practice on columns, beams, walls and slab. 1. The reinforcement arrangement should be always be staggered to avoid, or reduce likelihood of large cracks or spalling. 2. The staggered laps should not be located in areas of high moment. This is what Eurocode EC2 guidance is for column - 4% max generally, to 8% max at laps (although this is always less in reality by staggered laps) . Columns have to be designed to be ductile and hence limits apply. The concrete takes compression load, whilst reinforcement takes tensile loads. In slender columns the failure is most case is due to bending. Therefore best to stagger laps for better performance. There is a technical reason behind these max limits so best to work within them, otherwise also difficult to prove otherwise to checking engineers and authorities.

use staggered bar detailing at lap joint , by doing this , you can provide 5.25% steel in column instead of 4%, at lap joint column steel from above story will be half , so total steel at lap will be 5.25+5.25/2= 7.875% , which is less than 8% for IMRF . This detailed not applied to SMRF , as code restricted max column steel < 6%
