The Structural Engineer, Volume 41, Issue 10, 1963
The problem of fatigue in welded crane girders is introduced and its importance as a design criterion discussed. It is attributed to the local stresses generated in the top flange and upper part of the web of the girder beneath the crane wheels. Some significant stress patterns under these conditions are enumerated and discussed. A.G. Senior
A review of existing literature on epoxy concrete (in which glue is used in place of cement) and on the use of epoxy and polyester resins for joints in concrete shows that joints stronger than the concrete can be made but that poor surface preparation leads to a serious loss of strength. There is little information on the creep of joints under shear stress. R. PAUL JOHNSON
Dear Sir, With reference to the article, ‘The elastic analysis of simple rectangular grids by virtual work methods’ by J. B. Martin, BSc, PhD, appearing in The Structural Engineer in June 1963, I would like to point out that a numerical error has been committed in the solution for the numerical example given in the article.
