Hi everyone,
I’m working on a residential project where we have an RCC slab with a longer-than-usual span (~6.5m clear). While the basic design is as per IS456, I'm a bit concerned about potential deflection issues over time, especially with finishes and false ceilings involved. I’ve considered increasing depth and adding drop panels, but I’d love to hear what practical methods others have used in similar scenarios. Do you prefer using higher-grade concrete, post-tensioning, or integrating steel sections? Also, how do you usually monitor and account for long-term deflection?
Would really appreciate some insights or example projects if anyone has dealt with this.

Thanks in advance!
