 note = {The dynamical out-of-plane instability of a circular beam with a thin-walled double symmetric cross-section due to uniformly distributed radial loads, q=qo+qtcosτt, is investigated in the present paper. The method proposed by Bolotin are used to determine the boundary of instability regions. Equations used in analysis are nondimehsionalized by using the characteristic values of the out-of-plane buckling and vibration of the circular beam. These nondimensionalized equations yield the unified instability regions for beams with different cross-sectional constants and central angles., 長崎大学工学部研究報告, (4), pp.46-54; 1973},
