and Structural Analysis & Design
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
Sc
ience & 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 st
udent is encouraged to work with simple real life examples and to gain the skills and
understanding to develop effective and economic designs.

1
Bending moments and shear forces
Analyse cantilevers and simply supported beams
: evaluate cantilevers and simply supported
beams with a number of point loads and uniformly distributed loading, using
superposition
techniques determine the bending moment diagrams and shear force diagrams for the beams
Analyse three pin frames
: evaluate three pin frames with inclined, horizontal and vertical
members with a number of point loads and uniformly distributed
loading, determine the

Bending deflections
Bending deflections for cantilevers and simply supported beams
: Using Mohr's Moment

area
method, or Macauley’s method, determine the maximum deflec

supported beams of uniform section carrying a point load or an uniformly distributed load,
explore the effect of different materials and beam section on bending deflection in beams.

Delivery
Students will, in general, work individually, however some group work may be useful in
classroom situations. Em
phasis will be placed on manual analysis 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 with current design practice of comparing capacity with load rather than
applied stress to allowable stress.

be from areas associated with task management, numeracy and the application 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 and Design
. The in unit assessments and end
test will be designed to integrat
e this process as well as to satisfy the designated
learning
outcomes.
