The Hingeless Parabolic Arch . II Effect of Settlement of the Abutments

The general equations for the bending moment, horizontal thrust and shear force at the crown of a hingeless arch due to angular and linear movements of the abutment are obtained from strain-energy considerations. It is shown that all the quantities can be stated in terms of four variable parameters, for which nomograms are drawn for the case of the parabolic arch. An example is given, and the application of the nomograms to the solution of the arch equations for external loads and temperature changes is also indicated. R.J. Cornish
