Hello, Im using Autodesk robot structural analysis to design a 6 story building with flat slab (drop panels) system. when i design the floor i get many problems as follows:

 

 A
Plate704...731   
Problems with reinforcement arrangement 
It is impossible to obtain provided reinforcement with appropriate area. 
Too little top reinforcement area 
Too little bottom reinforcement area 
For panel no. 704 the minimum bar spacing:   1.5 [in] < 3.0 [in] is exceeded. 
For panel no. 714 the minimum bar spacing:   1.5 [in] < 3.0 [in] is exceeded. 
For panel no. 715 the minimum bar spacing:   1.5 [in] < 3.0 [in] is exceeded.
