Hello,

please some advice or guidance how to check the upper chord and lower chord in RSA regarding to the buckling lenth.

Thanks

Two ways:

1. superbar with 2 elements (4 of them)  ; in one direction buckling coeff 1, in second 0.5

2. superbar with 8 bars, then define Internal bracings accordingly and proper coeffs

hello,

please for confirmation and a advice for lower chord.

Thanks

Upper chord

Lower chord - if I understood your drwaing correctly

The beam top flange in compression is fully restrained because the concrete slabs are fully grouted and covered with a structural screed.

Thanks
