PRIME ENGINEER KILONZI :
most columns are designed to take compressive load rather than tension sir. buckling occurs at 0.5L for fixed-fixed supports. so lapping can never occur at column midpoint.

Khalid Budu :
But buckling risk is high at the middle. so basically the column over there, it lapping is wrong. please, can you explain further

Pls are u able to do another video to show us clearly de right lapping zone cus we can hardly see what you are trying to show us. I understand what you are explaining but we need more clarity with pictorial evidence. At what height is de lapping acceptable? Thanks

very true. dense stirrups at the bar and top.

Tony :
This is correct for short columns with with moments at the ends. We lap and provide sufficient lap length at the bottom because it is easy to construct. However if the column is slender, the maximum moment due to slenderness may occur in the centre depending on the end conditions and it is not advisable to lap in the centre. An effective way to provide the rebar is to stagger them.

Please, if I did not use, a starter pillar and I want to lab it at the top what would be the cause or effect and encase in that situation how many floors can I go with this ?

SMODA :
so where's the proper lapping zone sir? Are you suggesting the lapping should be done at the middle of the starter column?

tension??? happens only in lateral loads, eccentric loads. it distribute the laps at different heights for each bar. also it looks like an internal column so I'm confused to what is being said here
