Flexural cracks in beams
Kamranullah reacted to UmarMakhzumi for a topic
You can measure the deflection by using a thread and putting it across the floor and then seeing if floor is lower than the thread. Anyway, if the reinforcement works, that's fine. If it doesn't you should retrofit the beam. Thanks.1 point -
Column development length in Raft Inward or Outward
Hamza Irshad reacted to HAMMAD BASHIR for a topic
Hooks are provided for to resist seismic movement. To prevent concrete from splitting outward. It prevent slippage of steel from the concrete. In Detailing book M. Y. H. Bangash .

Column development length in Raft Inward or Outward
Hamza Irshad reacted to Badar (BAZ) for a topic
Yes, surely the mechanics of force transfer makes the hook redundant if development length is available. Code's language also suggests the same; the have used the phrase " if hooks are required...".1 point -

WSalaam, Cracking is not always bad. If J were you, I would re-check the design, get site reports on concrete strengths, confirm site placed rebars met development lengths and if all that works would let it go. Also other items you can do is to monitor deflection and get some NDT done if site information can’t be trusted. I am not sure about your comments on column orientation. Thanks.1 point -
ETABS - Global axis sign convention for base reactions
JL07 reacted to UmarMakhzumi for a topic
Hi JL07, I don’t have any CSI softwares installed but a quick way would be to model a simple column with fixed base and apply a moment to it and see how reactions are reported. I assume the right hand rule is being followed for +ve values but that’s my guess.. Do let me know if that works. Thanks.1 point -
Column development length in Raft Inward or Outward
Hamza Irshad reacted to Waqar Saleem for a topic
Salam, discussion is interesting, i have a query for my if raft is of 3ft or greater thickness, could rebars without bend can be used as the development length and embedment are satisfactory. Regards1 point
