The equations governing free, in-plane vibrations of variable curvature arches are derived and solved numerically to obtain frequencies and mode shapes for parabolic, sinusoidal and elliptic geometries. Included are experimental validations of the lowest four predicted frequencies and mode shapes fo

This paper provides a systematic approach to solve in-plane free vibrations of arches with variable curvature. The proposed approach basically introduces the concept of dynamic stiffness matrix into a series solution for in-plane vibrations of arches with variable curvature. An arch is decomposed in
Curved beams are more efficient in transfer of loads than straight beams because the transfer is effected by bending, shear and membrane action. The analysis of curved beams involves the solution of a sixth order ordinary differential equation derived by Rao and Sundararajan [1] which includes the e
