EUROCODESBackground and Applications Design process: Engineering inputs
Conceptual design: With the architect, developing overall concepts and structural forms
Scheme development: Developing structural schemes to the extent that defines general geometry – grids and approximate element sizes - and, potentially, costs
Detailed design: finalising all sizes and geometry and verifying the adequacy of the overall structure, its stability, and the strength and stability of all elements and connections – to a specific code.

Material prepared for use by practising engineers - in design practice
Very high pedagogical contentWill automatically be used for ‘informal’ e-
learningCan readily be adapted for formal e-learning
with:– Enhanced explanation, perhaps using existing electronic

EUROCODESBackground and Applications A Coda on e-learning 2
Traditional course market is decliningEmployers want their engineers to be able to
access their training:When they need it – for an immediate business needWhere they want it – at their workplace or at homeHow they want it – at their own pace
Employers will therefore increasingly want their staff to use e-learning
The big difficulty is to replace the interaction with lecturers and fellow students of a traditional course, by:
E-meetingsE-tutorialsEtc

Leonardo programme is sponsoring a pilot project on e-learning for steel design and construction
It will deliver:– 12 modules – Guidance on best practice for preparation of e-learning content
A simple questionnaire is available to guide the direction of this project
Input is needed, especially from practising engineers
