Why LUSAS for cable stayed bridges?
• Full linear and nonlinear analysis • Global and localised modelling of the structure• Full modal analysis on all, or parts of structure • Time step linear and nonlinear dynamics • Lumped mass modelling • Model proper cable analysis/behaviour • Staged construction modelling/analysis • Model differing degrees of member connectivity• Model damping of all, or parts of the structure

-
Cable tuning analysis
• Cable tuning facility calculates the initial equilibrium state.– Where the dead load of the structure and the forces in the cable
combine together to produce a structure that is at rest in the correct location.

Staged construction modelling
• Only one model file need be created to carry out an analysis of every stage of construction or dismantling
• Activate / deactivate model features and associated attributes
• Evaluate structural changes, load applications, and effects of geometric and material nonlinearity, and time-dependent material effects .
• Produce construction history tables

-
Time-stage analysis - Facilities
• Tree Definition of Time-Stages• Stages easily modified• View stages individually or
create animations• Stages can be activated and de-
activated
8LUSAS Post-tensioning and time stage analysis
-
Time-stage analysis - Facilities
• CEB-FIP Creep Model available
– Allows creep recovery• Define of age of concrete
and striking time• General creep models for
other materials
9LUSAS Post-tensioning and time stage analysis
-
Construction history tables• Allow for planning of construction dimensions to ensure final structure is the
shape required.• Also provide expected displacements when carrying out a dismantling analysis• Use for any type of structure• Specify points and loadcases of interest
– Time dependent effects (e.g. creep) can be included• Produce:
– Camber Table– Displacement History Table– Incremental Displacement History Table– Example tables follow
