Hi all,
PROBLEM: ASCE#7 WIND LOAD PARAMETERS - there is a change in displacement once global co-ordinates corporated.
I am doing a piping system connected to Pre-heater.
I have considered wind for this system & used ASCE#7 WIND LOAD PARAMETERS for wind cases,version CAESAR 5.0.
During my preliminary analysis I haven't incorporated the global co-ordinates(Y=000mm).System is safe in wind case.
But in the later stage, once I incorporated the Global co-ordinates(Y=644650mm), system fails in wind condition.
When we use ASCE#7 WIND LOAD PARAMETERS it doesn’t have effect in elevation wise, hence it same for all elevation. So if a pipe is place at 0 elevation or 20m elevation will have the same displacement as per ASCE#7 WIND LOAD PARAMETERS.
Whether the ASCE#7 wind load parameters will varies for elevation wise.
Regards,
BVK.
