Due to the deficit of section of web, the buckling strength of cellular beam become smaller than that of H-beam. In this thesis, we evaluate the buckling strength of web-post through non-linear F.E.M with opening distance-diameter ratio and opening diameter - web thickness ratio as essential variables. And also analyzes this comparing with the standard indicated in BS5950 Part 1.
