Description of Unit
This unit develops the student’s ability to analyse simple structures and produce an appropriate
design. The unit builds on techniques and understanding of structural behaviour developed in
Science & Materials.
The unit aims to
provide the student with the basic analysis and design knowledge required to
carry out the design of common structural elements to the appropriate British Standard, Code of
Practice or European Code of Practice.
The student is encouraged to work with sim
ple real life examples and to gain the skills and
understanding to develop effective and economic designs.

Delivery
Students will, in general, work individually, however some group work may be useful in
classroom situations. Emphasis will be placed on manual analy
sis techniques to determine the
values required for the subsequent design procedures. The designs of the structural elements can
be simple but will fully comply with the appropriate current standards. It is important that the
students become familiar wit
h current design practice of comparing capacity with load rather than
applied stress to allowable stress.

Common Skills should be assessed on 30% of the in unit assessment load and should
be from areas associated with team activities, testing processes, communication, task
management, numeracy and the app
lication of information technology.
Assessment Strategy
To assist learning, there will be frequent use of design problems to familiarise the student
with the process of
Structural Analysis & Design
. The in unit assessments and end test
will be designed t
o integrate this process as well as to satisfy the designated
learning
outcomes.
