Course Summary
|
Featuring three live online sessions of 90 - 120
minutes each, this course is
for engineers with a good understanding of linear analysis but who
need to progress to dynamic analysis for design and assessment.
Many problems facing designers and engineers are
dynamic in nature, whether it be vibration of a footbridge or impact
of an object hitting a structure. While the assumption of linearity
is routinely used for many designs with the application of dynamic
load factors, sometimes a more refined - dynamic - approach is
justified.
With LUSAS you can straightforwardly model the various forms of
dynamic behaviour that can be encountered, and become proficient in
using tools and facilities that are often seen to be the preserve of
the experts.

Obtain answers and practical engineering
guidance to the following:
- Understand why you need to move from linear to dynamic analysis.
- Appreciate the fundamentals of dynamic analysis whether it is a modal vibration problem or a true time step analysis.
- Appreciate why modal analysis can be used to predict vibration modes of your structure (as long as the structure itself behaves in a linear way).
- Consider why nonlinear transient dynamic analysis can deal with boundary conditions, and why structural responses are
nonlinear.
- Get an overview of the major application uses of dynamic analysis, from simple natural frequency calculations to time based seismic analysis and how to set them up in LUSAS
- Learn from practical dynamic examples including
assessment of a footbridge due to footfall induced vibration considering codes of practice.
Potential delegates should ensure
they are familiar with linear static analysis using LUSAS prior to
attending this course.

Notes
-
Training sessions
are provided using the GoToWebinar
web conferencing facility. You can join each training session up to 10 minutes before the scheduled start
time. They will start promptly.
-
Training sessions
are a mix of PowerPoint presentation and live demonstration
of LUSAS.
-
Delegates do
not undertake any hands-on examples during each session, but examples that cover the concepts introduced are provided for download and use by
delegates after each session. These examples will take between 45 and 60
minutes of offline self-study to complete. Email support is available from the
presenter to assist with these examples if needed.
-
Session
presentations can be downloaded from a training course event page
and printed off if required.
-
Delegates
are able to ask the presenter
questions during the training session via the chat tool or afterwards via email.
-
Sessions
are recorded and links to recordings will be provided to
delegates to allow viewing if a session is missed.
-
Training
certificates are provided to those who successfully complete the
series of worked examples and pass the quiz set after each
session.
-
Registration
for Session 1 is a requirement to attend all
subsequent sessions.
On successful completion
of the course, and with subsequent experience, delegates should be
able to successfully tackle many types of dynamic analyses that are
encountered in mainstream structural and bridge engineering.
LUSAS software version
LUSAS version 21 will be used to
present this course and is also required to undertake any offline
homework examples.

Typical Course Content
Session 1 -
Introduction to Linear Dynamics
 Learn
what linear dynamics actually involves with the use of basic examples not
complex theory. The chosen examples give different outcomes in linear and
dynamic approaches.
-
Overview of linear dynamics (modal analysis) and progression to modal superposition for designers to calculate design effects from dynamics situations to be used to assess/design structures.
-
Discussion on damping and why it is important to understand the damping level used for an analysis and the effect it has.
-
Presentation and homework example:
Linear modelling of a steel frame footbridge including both structural and
non-structural mass to assess basic modal dynamics on the structure.
-
Online quiz to complete the
session.
|
Session 2 - Transient
Dynamics
 Learn
why linear dynamics cannot be used in all cases and which scenarios require the
move to transient dynamics
-
Overview of transient dynamics
techniques using simple models to explore how to set up a transient dynamic
analysis and explore the results that are obtained.
-
Presentation and homework example: Modifying the steel frame footbridge
model created in session 1 to assess transient dynamics on the structure.
-
Online quiz to complete the session.
|
Session 3 –
Vibration Analysis of a Footbridge due to Pedestrian Excitation
 Understand
the process of assessing a footbridge for pedestrian induced vibration based on
design code requirements.
-
Understand the process of
assessing the dynamic behaviour of a footbridge and how to set up the
relevant analysis required.
-
Presentation and homework example: Dynamic
analysis of footbridge by initially assessing if the footbridge is likely to
have dynamic issues and then progressing to calculating the actual response
of the bridge and checking results against design code limits.
-
Online quiz to complete the session.
