Thanks everyone for the valuable thoughts on the subject

@greenalleycat - same here. It's not the anchor itself. Pullout strength in concrete will be very less for cracked concrete. I thought it's more for the installation of anchors on suspended concrete member because of the formation of cracks due to bending. @DaveAtkins - sorry, did you mean...

@greenalleycat & @Tomfh Thanks for your input on this. Looks like everyone is on the same page that nobody knows why 1170 says midspan. I think its best to go with the H/300 for knee till the code revises. ;) Thanks again.

Hi all, Thank you for your explanation. I also agree with you that it could be a typo. Funny thing is its been referenced in these papers. For eg the one I shared. It says midspan. Another thought is, the load case/combination mentioned in 1170 is only for wind sls. Not for seismic. So, does...

Hi all, Thank you for sharing your thoughts. There is another paper ( Link below ) https://repo.nzsee.org.nz/bitstream/handle/nzsee/2591/Liu.pdf?sequence=1&isAllowed=y The second paragraph of section 5 says the height as different. The first few lines referring 1170 says the sls limit is...
