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.

EUROCODESBackground and Applications A Coda on e-learning 1 role of A-S

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

resources, e. g. SteelCAL– Formal assessment

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

EUROCODESBackground and Applications A Coda on e-learning 3

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
