Hi danb,
If that is the case then Caesar must be wrong. The wind speed I used was 45m/s which is less than 60m/s which means that the loading does not change. You are correct when I changed the wind velocity to 70 m/s then the loads varied vs height. Strange how the wind loading changes for all of the rest of the Codes which can be chosen except for the ASCE Code. Thinking logically the wind loading is the wind loading and the wind pressure must change vs height no matter what the wind speed is - it is pure physics. The wind profile changes versus height.
