TH with 2nd floor concrete over wood subfloor deflection concerns

Hi all. Jesse from Houston here. handyman thrown into reconstruction/remodeling after Harvey. Still 'green" so I'm here looking for advice on how to proceed with a tub to shower conversion on a second floor Townhome bath when it comes to the shower floor structure.
the removal of the cast iron tub unveiled 2" thick concrete over plywood (i'll try and attach a pic) .The concern is the concrete has cracks through it.
I believe its safe to assume that there is enough deflection to potentially cause problems and the question is what do I need to do before I install a pan in this case?. I'll measure the joist tomorrow but by the looks its probably 2x10 or 2x12. the "head scratcher" for me is how to enter this scenario in the deflecto calculator. joists hang from a beam (sistered joist) under the shower floor. Any suggestions or recommendations would be greatly appreciated.Name:  concrete floor .25.jpg
