Static linear analysis
Static nonlinear analysis
- Force or displacement control
- Staged construction (construction sequence loading), including
multiple scenarios
- For the special case of pushover analysis includes effective damping
computations, capacity spectrum computations and demand spectrum
comparisons are also performed
- Nonlinear frame, cable and link elements
- P-Delta analysis
Large displacement analysis
Modal analysis
- Eigen analysis with an accelerated subspace iteration algorithm
- Ritz analysis for optimal mode superposition basis
- Modes can include P-delta, large displacement and construction
effects
Dynamic response spectrum analysis
- Modal combination by the SRSS, GMC(Gupta), 10 Percent , and Double
Sum methods
- Directional combination by the SRSS or factored absolute sum method
Dynamic linear and nonlinear time history analysis
- Use either the Wilson FNA method or a direct integration method
- Ground acceleration excitation
- Multiple base excitation
- Load forcing functions
- Transient or steady state
- Nonlinear frame, cable and link elements
- Geometric nonlinearity
- Wide variety of integration methods
- Graphic and tabular displays of nodal and element time history
records
- Functions versus time or function versus function displays
- Generation of response spectrum curves for any joint acceleration
component
Bridge analysis (Moving load analysis)
 
- Generation of influence lines and force envelope
- AASHTO vehicle loads
- User defined truck, lane and train loads
- Determination of maximum and minimum displacements and reactions
