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been superceded by later LUSAS software releases.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.
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:
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)
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)
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)
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)
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)
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)
