An arch is a curved structure in its elevation, loaded in-plane having supports are prevented from stretching out, and loads are supported mainly in compression. Arches are extensively used in infrastructure projects to provide large span structures, especially in bridges owing to its effective load carrying mechanism. For the case study, a 60m clear span standard bowstring is analyzed. The study has been done for comparison of buckling factor given in Eurocode 3: part 2 with the model analyzed.
