Siren Overview
Siren allows investigation of a site response to a seismic
event.
General features:
- Wizards to guide users in setting up the
model
- Units can be chosen from preset SI, kN-m,
kip-ft of kip-in unit sets or specified individually for each
component
- Import of excitation time-histories in a
variety of formats
- Graphical representation of results
- Data checking to identify invalid or
inconsistent data
In Siren the site is modeled as a column of soil overlying
bedrock. Properties are assigned to the bedrock and the soil which
is modeled as a non-linear stress-strain curve which incorporates
hysteresis effects. Excitation is assumed to apply at the bedrock
level and an explicit time integration scheme is used to calculate
the soil response with time.
Features
- Multiple soil stress-strain curves and transmitting or
non-transmitting boundaries
- Control of integration time step and output time step
- Graphical output of time histories: displacements,
velocities, accelerations, stresses and strains
- Graphical output of stress-strain histories
- Calculation of response spectra
- Export to Sigraph for post-processing
The user documentation gives full details of the capability of
Siren. This is available both in
PDF format and In online format from the Help menu within the
program.
