I am working of a factory building,
But after importing & designing in Staad RCDC its showing -"Detailing failure ".
By the way I have tried a lot of dimensions[(18"*24"),(24"*24"),(30"*30"),(20"*16"),(36"*36")] but neither of them worked .
Columns beneath are (600*600) & (450*750)mm
its a 4-stored building.
