Dear Members
 
	I am working on a project site where Column Reinforcement is as shown in the file.  
	The Columns (C6 to C20) are going from +12'-0" to +48'-0" un-braced and without any slab at intermediate levels. The slab is at +12'0" and +48'0" level. 
	The Reinf is changing and larger dia bars are provided on top. 
	I want to ask that is it alright and what is the possible explanation of changing the number and dia of bars in-between ?  
	Regards
