According to the requirements of the atlas, can the column reinforcement within two floors overlap?

According to the requirements of the atlas, can the column reinforcement within two floors be set with a lap height of 3 meters? I think the column longitudinal reinforcement should be provided with a joint every other layer, but the supervisor disagrees. Is it necessary to have one on each floor? Answer: I support your idea. No matter in the Code for Design of Columns and Beams of Concrete Structures (GB500 10), there is one item for reinforced joints: ... reinforced joints should be set in places with less stress. There should be fewer joints on the same steel bar. Can you ask the supervisor? How to understand this statement? For longitudinal bars that are difficult to guide, is it worse to set a joint every other layer than to set a joint layer by layer? Due to the limited length of steel before leaving the factory, and the short cut materials should be fully utilized, the specification and atlas require that the lap joint be set at the specified position. How can we meet the requirements of specifications and atlas, but we should set up joints in different levels? As few connectors as possible! Safe and economical! Why not? I think your "supervisor" doesn't understand the structure and norms at all. He just sticks to this atlas and doesn't understand it. What a joke! How can I become a "supervisor"? I sent him a sentence: study hard! Read dead books! Read this book to death.
