The pace of change in IT is breathtaking and the hype is even faster! One thing is for sure, though, there are great opportunities opening up for all of us and this includes our own Institution.
The paper describes the method of calculation of the buckling load of beams on flexible bearings due to the beam’s self weight. Methods are given that allow calculation of the bearing stiffness needed to prevent instability, as well as the additional curvature and additional stresses due to the growth of initial imperfections at loads less than the critical load. Methods of providing temporary support and of jacking beams into position are also discussed.

This theme, addressed by John Graham (Verulam, 2 January 2001)has clearly interested
many members, who have provided helpful advice. Martin Elvidge from Bradford writes:
John Graham of Quorn, Leics., should take a look at Bruce Irons’ solution to the problem of solving finite element equations. His elegant frontal system cured the problem of limited storage in 1970 using much inferior computers to those available today. It takes advantage of the fact that contributions to variables in the structure matrix are complete unless there are other elements connected to it. It is therefore
possible to assemble the matrix and eliminate variables at the same time, thus saving computer storage.
