The virtual work equation by which flexural deformations are related has been corrected to allow for the effect of axial compressive forces. These corrections can be applied wherever the end moments on an axially loaded member are defined and are particularly useful in the determination of the elastic critical loads of structural systems by reiterative numerical methods.

This paper presents a method of determining influence lines involving the use of Muller-Breslau's principle and the direct distribution of deformation. The method is applicable, generally, to continuous beams, symmetrical or unsymmetrical frames, and structures with prismatic or non-prismatic members. Alan Williams
At the meeting a number of members contributed to a discussion on Dr. Plowman's paper and their comments were recorded by the Institution's shorthand writer, Mr. A. R. Purchase, whose death was announced a day or two later. Despite many efforts it has proved impossible to transcribe Mr. Purchase's notes. The written contributions to the discussion are published below, with Dr. Plowman's replies. The Institution offers its apologies to Dr. Plowman and to those members who spoke at the meeting for the fact that publication of the full discussion is impossible.
