Dear All,

From CII Technical Reference, we know that the wind shape factor is based on ASCE #7 figure6-21 between 0.5 to 0.7.

In case our piping is on the pipe rack, where few pipes are parallel together, theoretically, the pipe in the middle of the pipe rack should not exposed to wind as much as the pipe at sides. Does Caesar consider this kind of consideration?

In addition, if my pipe is at elevation 20m, is that means that I have to edit the global coordinate to DY = 20m? SO that this will be considered by the Caesar II when analyzing the wind effect. I am using the wind pressure vs elevation input.

Thank you.

1. No, it is impossible for Caesar to know if your line is in the middle of piperack.
2. No, you should define the real global coordinate of the first node.

Regards,

Actually the answer to #2 is "yes", you do need to set (edit ?) the global Y coordinate of the first node so that its elevation is correct.

The elevation (alt G) used in Caesar II shall be the ELEVATION ABOVE GRADE.

Dear All,

Thank you so much.

Have a nice day (^_*)
