The Structural Engineer, Volume 79, Issue 6, 2001
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.
The Government of Orissa (GOO), India, has been constructing health-care infrastructure in collaboration with the UK Department For International Development (DFID), under the Basic Programme. The commonly used building materials in such construction works are laterite and brick, which have a detrimental effect on the environment. Hence, Go0 and DFID decided to try out alternatives to these materials. Peu B. Das and P.K. Das
Building Control Bodies are responsible for examining plans submitted by applicants and judging whether the construction of a building could comply with various Parts of Schedule 1 of Building Regulations. For demonstrating compliance with Part A (structural safety), applications include structural calculations and drawings. For small projects, structural drawings, sketches and calculations are presented with some wide degree of variation concerning their clarity and effectiveness in demonstrating adequacy of the design. Some issues arising from checking such work are discussed below, including a case for practical guidance aimed at improving the standard of submissions. Satish Desai
