LUSAS Bridge Modelling: Grillage Analysis

Course Summary

Featuring two online sessions of between 90-120 minutes each, this course provides engineers with a good understanding of the relevant facilities within LUSAS to carry out grillage (or grid) modelling and analysis.

Grillage (or grid) modelling remains a very popular method for analysing bridge decks because it is relatively easy to comprehend, computationally inexpensive, and proven to be sufficiently accurate for a wide variety of bridge types.

Learn about the modelling methodology, loading facilities, interpreting the results, and the limitations of the method and identifying alternatives.


Learn about and obtain practical engineering guidance to the following: 
  • Basic concepts of grillage analysis including discussions on layout and limitations. 
  • When it is appropriate to use a grillage analysis and when it is not 
  • Efficient data preparation and calculation of section properties 
  • How to incorporate a staged construction sequence into the grillage analysis 
  • The effect of the application of highway and rail loads as part of the analysis process
  • Learn from practical examples including slab decks and composite bridges with bracing

Bookings and payments

  • To book and pay for a single place on a course click the 'Book now' button. If multiple bookings of staff from the same organisation are required with payment to be made via a single invoice, please contact the training course administrator at

  • Course costs include handouts and are quoted in local currencies and are exclusive of any local government taxes (if applicable). 

  • Please note that when paying by credit card the amount charged in your currency may differ according to exchange rates and credit card fees incurred, which are beyond our control.

  • For cancellations to attend a training course that are received in writing at least 1 day prior to the first session taking place, the course cost will be refunded.

  • LUSAS reserves the right to reject bookings and to cancel or re-schedule courses or individual sessions in the unlikely event of this being required.

On successful completion of the course, and with subsequent experience, delegates should be able to successfully tackle most types of linear static structural analyses that are encountered in mainstream structural and bridge engineering.

Online training information

Sessions presented using Session length After session offline self-study required Training certificates
GoToWebinar 90 to 120 minutes 45 to 60 minutes Issued on successful completion 


  • 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.

LUSAS software version

LUSAS version 21 will be used to present this course and is also required to undertake any offline homework examples that may be provided..

Accessing LUSAS 

Individuals who wish to attend the training who do not have access to the required version of the software may request a temporary training licence from LUSAS to allow the running of the software on their personal computers. After booking your place on the course, please contact to request a licence stating your name and details as asked for on the booking form.

Typical Course Content

Session 1 - Introduction to Grillage Analysis 

Learn how to undertake a simple grillage analysis with the use of basic examples not complex theory.

  • Overview of the basic concepts of grillage analysis (layout, dimensions, spacing, skews, etc).
  • Efficient data preparation focusing on section properties.
  • Use of multiple analyses to consider short and long term properties.
  • Effective application of highway or rail traffic loads.
  • Presentation and homework example: Concrete slab deck with highway traffic loading.
  • Online quiz to complete the session.

Session 2 - Advanced Grillage Analysis

Having gained basic knowledge of grillage analysis, this session will provide details on how to analyse more complex structures.

  • Building on session one, more complex bridge structures, such as multi-span composite bridges and box bridges will be discussed, covering how they can be modelled.
  • When grillage analysis is appropriate and when limitations would require more advanced analysis
  • How to incorporate bracing into the grillage model.
  • Understand how to efficiently consider and incorporate a staged construction process into the analysis model
  • Presentation and homework example: Multi-span composite bridge with bracing.
  • 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.)
