Abstract:
For circular archs having a ratio of thickness to mean radius greater than 0.3, a central angle less than 100 deg, and under normal loads, high tensile stresses are indicated both at the crown and at the abutments by the usual formulas. A method of computation is proposed which assumes that the stress distribution is linear on radical sections and that the part of the arch not subject to compression may be disregarded.
