# The Hingeless Parabolic Arch. I. Exact Solution of the Elastic Equations

*The elastic equations of the hingeless arch are usually solved approximately by dividing the arch rib into a number of sections. In the case of the arch whose axis is a parabola and in which the depth varies parabolically from crown to springing, an exact solution is possible, even if ribshortening is taken into account.
