Vertical Braces - RISA 3D
Vertical Braces - RISA 3D
(OP)
Have a RISA-3D model / analysis of steel framed mezzanine. By going through the results, how can one tell the vertical braces (Cross type for instance) will be required between the columns?
Thanks,

1. Make sure you have member moments released where it should be.
2. I think it's a good step to replace your fixed BCs with varying stiffness of springs just to check how moments redistribute and deflection is affected.
3. A apply a lateral load to the mezzanine of 1% D+L with pdelta turned on. More it is is a public mezzanine. More like 10%.
