plate girder design -AISC-360-05/10
Hi everyone !   I am designing an aircraft hangar 50m (span) *30 m , i can't limit the node displacement with an economical design using the AISC ASD because the plate girder design is not...

I do not appear to reproduce these problems in a sample model here. I see that x-bar is taken as the distance from the faying surface to the centroid of the member and see U=0.9 for the flange...

I was running a design for a WT vertical brace and found what I believe to be a mistake in the calculation of the shear lag factor, U, for tensile rupture. I have (7) rows of bolts connecting the WT...

This means that the applied loading in LC 3 does not cause buckling of the structure.
View ArticleRE: Urgent help on Buckling analysis
Thanks modestas. So does that mean we can rule out all the positive load cases/upward forces conditions in buckling analysis, if no buckling is caused when the same load value is applied in negative?...
View ArticleRE: Urgent help on Buckling analysis
If the applied load is not causing buckling, then there is no need to perform buckling analysis of it. You can use the repeat load with -1 factor to change the direction of the loading and get the...

Thanks Modestas. I tried that and no buckling is occurring if i change the direction of the load. however when the repeat is done with -1 factor **WARNING- THE LOADS IN CASE 3 ARE IN THE OPPOSITE...
View ArticleRE: How to arrive at the value of the parameter DFF ?
The DFF value is guided by the respective design codes. The (Span/DFF) is the maximum allowable deflection.
