Hi, I am trying to use plate elements to design a suspended concrete floor to support two 6000ltr tanks. I have modelled patch load to represent the tank load. I am trying to find out maximum moment in slab (Plate element) . Results I am getting don't look right especially when compared with hand calculations. I think I am using the plate elements incorrectly. could somebody check my attached file and advise whether I have modelled the plates correctly, and also advise how to apply patch load on a meshed plate. Thanks
