Abstract:
In this paper, based on the classical linear theory, both radial and tangential displacement components of buckling were considered. The equilibrium equations and connection conditions at the middle hinge were derived from Trefftz's stability criterion for buckling and the transcendental equations were derived for use in determining buckling loads of a uniformly compressed nonsymmetri-cal three-hinged circular arch with variable cross sections. Finally, the results calculated were compared with Dinnik' s for the case of symmetrical three-hinged circular arch with uniform cross section
Key words: three-hinged circular arch, buckling loads, transce- ndental equatations
