Excerpt from Selected Papers of the Rensselaer Society of Engineers, Vol. 2: January 1894 A proper consideration of all the influences existing will not demonstrate the instability of a structure which stands with every evidence of security. In the treatment which follows, the ring stones will be considered to be unchangeable in shape, or perfectly rigid. This hypothesis eliminates from the question all consideration of the condition of the ends of the arch at the skew-backs, and is not only admissible, but necessary, as the nearest approach to the actual condition of things. There is probably no arch in existence in which perfect continuity from skew-back to skew back has been preserved after the removal of the centre. If the arch is assumed to be elastic, and fixed at the ends, this con tinuity must not only be absolutely perfect and extend through the skew-backs, but the whole structure must settle uniformly. If the ends are assumed to be hinged, continuity must hold between the skew-backs, and uniform settlement must take place. In consequence of the number of joints which are observed to open in many existing arches, even upon hasty examination it is in the highest degree probable that neither perfect continuity nor perfectly uniform settlement occurs in any case. It is, therefore, necessary to make the case one of pure statics only, instead of combined statics and strains.
