Abstract

The static bifurcations of planar circular uniform arches subjected to a point load, applied at the keystone, are investigated. The secondary paths of the nonlinear buckled solutions are also determined. Moreover, the natural frequencies and mode shapes of vibration around the fundamental and bifurcated arch equilibrium configurations are studied. The influence of a localized damage at the keystone on the arch stability and vibration properties is discussed; interesting features about the structural stability of the arch bifurcations are accordingly disclosed.
