Understanding Basic Dynamics - Modal to Time-step Analysis

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.

GoToWebinar 90 to 120 minutes 45 to 60 minutes Issued on successful completion 

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 lecturer 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 lecturer 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.

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.


Some delegate feedback from LUSAS scheduled training courses:

  • “This class was excellent and one of the best training courses that I have taken." (Tim E.)

  • “Very good demonstrations/teachers with a good variety of hands-on examples.” (Douglas R.)

  • "The instructor was phenomenal! Engaged, energetic, helpful and friendly! Could not have asked for a better one." (Joe K.)
