Hi, I am familiar with (1:1) the aspect ratio with square plate elements, and also the acceptable ratio up to 1:4. Can anyone tell me what is the preferred aspect ratio (length-to-thickness) of plate elements and solid elements in STAAD? Is there any boundary related to 1:10?Now, I'm modeling a 2.5m thick slab with 0.5mx0.5m mesh size plates, should I be careful with the length-to-thickness ratio as it is now 1:5?
