Please refer steel tables book. By calculating I got the area of the cross section which 10769, so I chose ISMC 350@413 n/m, Area of the is channel section is 5366, here in this problem we are choosing 2 ISMC sections so, 5366+5366=10732, which is nearer to 10769 i.e ISMC 350@413 channel. Like that you have to choose the section.
