Sažetak
Helical girders being a 3D structure presents a problem when analytical solutions are concerned. Some researches such as A. Engle (1955.) and V. R. Bergman (1956.) offered a solution by idealizing the structure as a 2D problem, but the results were highly conservative and inaccurate. A. Holmes (1957.), V. A. Morgan and A. C. Scordelis (1960.) presented a solution to internal moments by observing the structure as a 3D model [1-2]. Morgan’s method was shown to gain most reliable results when talking about steel girders and although his approach seems most sensible compared to others, it is computationally demanding.
