Engineering analysis and design software
Any structure. One solution.

Older LUSAS videos

Please note these videos, that show some general capabilities, have now been superceded by later LUSAS software releases. As a result, current methods of model creation, analysis capabilities and results processing techniques, may differ from those shown. 

LUSAS Version 14 videos

The LUSAS presentations listed on this page are supplied in MP4 or streaming Shockwave Flash format (.SWF) and include audio. The presentation duration is stated after the title. Note that whilst metric or imperial sets of units may be used in these presentations, analysis with any consistent set of units is generally permitted in LUSAS.

Video controls and a full screen option are provided at the bottom of each video during playback:


Modelling of a bowstring arch footbridge (7:15)

  • A steel bowstring arch footbridge is modelled in readiness for a subsequent eigenvalue analysis and dynamic assessment to a design code. (Version 14.7-10)


Eigenvalue buckling load factor analysis of a bowstring arch footbridge (3:52)

  • Setting up of eigenvalue analysis controls to ascertain critical load buckling factor, which is then viewed as an animation. (Version 14.7-10)


Footbridge dynamics assessment to the Sétra code  (7:22)

  • Pedestrian induced loading assessment on a bowstring arch footbridge according to Sétra .(Version 14.7-10)


Simple staged construction of a cable staged bridge (3:43)

  • Short presentation to show how parts of the bridge structure can be activated to replicate the stage construction process. (Version 14)


Straight girder buckling (19:22)

  • A model of a pair of braced 'I' girders representing a footbridge is built from scratch showing the associative modelling, meshing, loading and support features of LUSAS. A linear static analysis is carried out followed by an eigenvalue analysis to ascertain the critical mode shape in order to calculate the critical buckling load. (Version 14)


3-span bridge deck - simple modelling (13:02)

  • A 3-span skewed bridge is built showing the associative modelling features of LUSAS, and then loaded with self-weight and an AASHTO LRFD truck loadcase.(Version 14)


3-span bridge deck - basic results processing (9:09)

  • Deformed shapes for each loadcase are viewed and contour plots investigated. Results are graphed using longitudinal slicing along the model; smart load combinations are defined and printed, and detailed results are listed. (Version 14)


Introduction to the LUSAS V14 User Interface (5:43)
  • General overview of using the LUSAS user interface for Version 14.0

Simple building frame modelling and results viewing (16:20)
  • Creation of a 3D steel frame building with concrete floor panels. Shows general beam and shell modelling, selection and orientation of steel sections, defining eccentricities and plotting of results in both contour and diagram formats on all and selected parts of the structure. (Version 14.0)

Boolean geometry modelling (6:13)

  • Creation of a quarter model of a metal component using boolean union, subtraction and intersection methods before meshing, solving and viewing results on a slice through the model. (Version 14.0)
