Three types of software can be found on this page regarding the
simulation of earthquake strong motion ....
..... time histories (acceleration,
velocity, etc. Stochastic Approach)
..... parameters (peak ground acceleration, PSV, PSA, etc.
Stochastic Approach)
..... time histories compatible with a user specified
response spectra
Any questions or comments regarding the codes or their usage
should be submitted using the forms on the Feedback
page.
UPDATE - 2004/07/14:
Simulation of Strong Ground Motion
The specific barrier model has recently been calibrated to earthquakes of
inter-plate, intra-plate and extensional regime earthquakes. The corresponding
SGMS and SGMP codes and user manuals are in the process of being made available
on this page. These codes will eventually replace the older versions SGMS_ENA
and SGMP_ENA.
Please refer to the Strong Motion Synthesis page and
a recent
presentation for an overview of the methods and approaches that we have
taken for strong ground motion simulations.
In the meantime, please use the Feedback page on
this website or email
Benedikt Halldorsson to inquire about the updates and/or the usage of the
codes:
Strong Ground Motion Simulation (of time histories)
Code: SGMS (v5).
User
manual: Draft.
Strong Ground Motion Parameters (of e.g., PGA, PSV etc)
Code: SGMP (v5).
User
manual: See the included sample
input file for information until the user manual is completed.

| An updated and extended version of the above code is RSCTH
(Response Spectrum Compatible Time Histories). For details,
refer to the comments in the input file for explanations and compare with
TARSCTHS.inp. Also, a user manual is on the way
 |
The main changes are that the empirical response spectra
of Boore et al. (1997) for California have been incorporated into the
TARSCHTS code and its name was changed. The user can now specify if an
empirical spectrum should be used, and the output time histories will be
compatible with that spectrum. Also, the maximum number of points in the
user defined spectrum is now 100 instead of 20 before. This code will
eventually replace TARSCTHS. |
