Wind load Not applied properly

Dear Engineers,

(a) I have problem in applying wind load to my model.Its not applying properly.I have attached model for reference.../

(b) Also i have another doubt that i have given the bottom slab as 250mm and 500mm thick.

The 500mm thick slab top and 250mm thick slab top should be same ,

but not same in staad model because both slab center region is same../(check in rendering view)

What can i do , is this will affect my result..

(c) Also i'm facing an warning message, but i do not why ?

6765.sample.std"*WARNING- NO MEMBERS LOADED FOR A FLOOR LOAD GENERATION. "

  • The wind load generation is also failing due to the same issue of the nodes 526 to 529 lying slightly out of plane. The tolerances for wind load generation are even tighter than that used by the floor load algorithm. So here is what I would suggest. From the startup page go to Configuration and change the Significant digits to 6 as shown.

    This would ensure that sufficient number of decimal places are retained in joint coordinates and the Y coordinate of 2.5037 m does not get rounded off to 2.504m. I have changed the Y coordinates to 2.5037 for these nodes and this took care of wind load and also the floor load. With this change you would not need to use the SET FLOOR LOAD TOLERANCE command anymore. A modified file is attached.

    The bottom of the pedestal and slab not being at the same elevation is more of a detailing thing and I don’t think it would have any significant impact on the analysis.
