Hi,
I have a diaphragm force of 420kips (ASD) being resisted in a slab whose diaphragm capacity is 3500lbs/ft. 420kips is resulting is a diaphragm force of 4500lbs/ft. So the diaphragm does not work. What are the alternatives to resist this diaphragm force with out increasing the slab thickness? Is adding reinforcement an option? If reinforcement is added, do I need to size the reinforcement for full 420 kips of capacity or just the difference (1000lbs/ft)?
Any other way of resisting the diaphragm force?
The force 420kips is resulting form the ASCE Eq 12.10-2 and not from analysis. The analysis force is just 210kips.
Thanks
