Questions about Wind Load Generator and some more in Leap Bridge Substructure

Question

Hi, Dear All, 
 Could you please let me know how the Z is calculated in the wind load generator? 
 
 How do we deal with the wind load on the crush wall which is under the column but above the footing? 
 Also, what is the best practice to enter the buoyancy load in the substructure model? 
 Please advise. 
 Thanks, 
 Dong

I shall try to answer one question at a time. 
 Z = Total height from bottom of the column till top of the barrier.

For more information related to Wind load please check the wiki articles in the below mentioned Bentley Communities link.

Currently the program is not applying the wind load on Crash wall. 
 The workaround solution is to calculate the equivalent wind load and apply that load at the bottom of the column, as shown in the attached screenshot. 
 I hope it helps.

Also, what is the best practice to enter the buoyancy load in the substructure model? 
 Buoyancy can be input only as a manual load. 
 This is an uplift force that can be input at the base of the column in Y-direction. 
 For more information related to Buoyancy, please check the below community's link.
