Wider RC Beams, Small Column
Wider RC Beams, Small Column
(OP)
Dear All,
I wish to seek advice and guide on how to tackle this problem.
Currently, we are designing a four storey shop/residential buildings with two level of basements. At one of the floor, as an alternative to post-tensioned beams, we are thinking of doing a wider RC beam (1800x700) while our column is roughly 450x450. (see attached picture)
What check shall I be doing? Using the software, it tells shear in the beam is okay. The beam does not fail. However, I would also like to do manual calculations for this.
What other check shall I carry out? Punching shear?
Thanks for your help!

I like to debate structural engineering theory -- a lot. If I challenge you on something, know that I'm doing so because I respect your opinion enough to either change it or adopt it.

I did not encounter that check in my code also. How do you do checking for punching shear in the beam? Mind to illustrate how that detail is?
Yup, there is column transfer also in it. Was thinking to the haunch at the part where the column transfers are.

Just like you'd do it for a slab.
That sounds like expensive formwork. I'd try to make it work it stirrups etc.
