Dear All,
Currently i'm designing a gantry crane.
1. I have assigned the loading from Crab to the gantry beam as moving load (Shows in Red color), But i have no idea how to assign the loading (Shows in Green color) when gantry crane is moving along Z axis. Can anybody explain me how can i assigned this load or any assumption should i take.
2. I know i should assign impact load to the structure, to do that i think i have to assign Time History, but which nodes in this structure i should assign time history?
I have attached my STAAD input here, it would be great if someone can check and let me know, is there any things should i add.
Thanks in advance
