I have applied wind to my model at the Initial stage, to check the bare steel under its self weight + wind and at Final, to perform the standard Strength I, III, V checks. I would like some clarifications: How is the wind applied? In the wind input form, I checked user input and input a pressure. Will Leap determine the load on the flange (k/ft) per LRFD 8 th 4.6.2.7.1-1? In the initial condition ( steel only), will LEAP apply wind to all beams, top and bottom flange? And if not , how can I achieve this? In the final condition , will LEAP apply wind to the bottom flange of the fascia girders only? And if not , how can I achieve this? Is LEAP computing the wind moment and stresses per LRFD 8 th C4.6.3.2.7.1-3? And if not , what calculations does it use? Thanks, Leo Marcatelli

LEAP Steel Wind Load Application and Lateral Moments

I have applied wind to my model at the Initial stage, to check the bare steel under its self weight + wind and at Final, to perform the standard Strength I, III, V checks.

I would like some clarifications:

How is the wind applied? In the wind input form, I checked user input and input a pressure. Will Leap determine the load on the flange (k/ft) per LRFD 8^th 4.6.2.7.1-1?
In the initial condition ( steel only), will LEAP apply wind to all beams, top and bottom flange? And if not , how can I achieve this?
In the final condition , will LEAP apply wind to the bottom flange of the fascia girders only? And if not , how can I achieve this?
Is LEAP computing the wind moment and stresses per LRFD 8^th C4.6.3.2.7.1-3? And if not , what calculations does it use?
