Engineering Structures - STRC 201 - Home Page

1 Introduction
Staff teaching this module: Jeff Barlow and David Grieve, both have offices in the Reynolds Building.
This module covers the areas that need to be considered when designing structures. These include: statics, vibration, fabrication and corrosion.

2. Assessment
This module is assessed by a combination of examination (70% weighting) and course work (30% weighting - split 0.4 for thin cylinder lab and 0.6 for the analysis of the engineering component).

3. Course Work
There are two pieces of course work:
i) Thin cylinder experiment, done in groups during weeks commencing 13th to 27th October 2003.
Link to information about the thin cylinder experiment
NB Note changed hand in date The hand in date for this report is 4pm Wednesday 18th February 2004.
ii) Structural analysis of an engineering component. Separate information is available about this. The report must be handed in by 4pm on Thursday 18th March.

4. Links to learning support material. Some of these links, below, are to pages which contain 'Engineering Science - MECH 226' in their heading - this is because MECH 226 covers a lot of similar material to this module.
Normally DJG will lecture in the 9.00-10.00 am slot and JWB in the 10.00-11.00am slot, but this will be varied depending upon other demands on peoples time.

The table below is a preliminary programme which will be varied according to student needs.
NB The dates for handing in course work can not be changed unless there are exceptional circumstances.
