THE VARIATIONAL THEORY OF A CIRCULAR ARCH WITH TORSIONAL SPRINGS AT BOTH EDGES
Minkyu Kwak, Jaegwi Go
Pages. 11-15     



The behavior of arches are nonlinear and sensitive to the
buckling conditions. The existence of equilibrium states of elastic
circular arches with rotational resistance at both edges under
normal pressure is investigated. Variational formulation is derived
using an energy method.
