| Title: | Second-order direct analysis of steel structures made of tapered members | Authors: | Chan, SL Liu, SW Liu, YP |
Issue Date: | 2018 | Source: | Proceedings of the 12th International Conference on Advances in Steel-Concrete Composite Structures (ASCCS 2018), Jun 27-29, 2018, University of Politecnica Valencia, Valencia, Spain 2018, p. 75-82 | Abstract: | Mild steel hot-rolled sections are commonly prismatic because of the rolling process with a furnace, but welded sections made from steel plates do not have such a constraint, especially when robotic welding machines are used. The weight saving could be very significant by, say, using wide flanged section at mid-span and a small flanged section at ends of a simply supported beam. However, design codes do not provide formulae for buckling check of tapered members. This paper proposes a code-free second-order direct analysis for stabilty design of steel frames made of tapered members. The design is further applied to a single layered mega space frame of 136m span. In the whole design process based on the concept of Second-order Direct Analysis, no uncertain effective length and independent member buckling checking are required. | Keywords: | Tapered members Stability design Buckling Steel frames |
