A numerical method due to Newmark, extended to plane curved members, has immediate practical application in the buckling analysis of arches and rings of arbitrary shape, cross-section variation and load variation. Examples show that the method is capable of the accurate practical solution of many problems which defy solution by advanced mathematical methods.
An extended moment and force distribution method is presented for the analysis of plane frames by electronic computers. The method is developed to give the solution for orthogonal frameworks of arbitrary shape with respect to the effect of axial deformations, settlements and temperature changes. The results of the analysis show the moments and shear and axial forces in the members, as well as the displacements and rotation of the joints.
Owing to Mr. Keating’s absence abroad, his paper was presented by Mr. Patrick Garland.
