RSSeismic Overview
RSSeismic is a one-dimensional site response analysis program for performing:
- 1-D finite-element based analysis with uni- and bi-directional shaking, with and without pore pressure generation
- 1-D lumped-mass-model-based nonlinear time domain analyses with and without pore water pressure generation
- 1-D equivalent linear frequency domain analyses including convolution and deconvolution
- 1-D linear time and frequency domain analyses
The purpose of RSSeismic is to make site response analysis readily accessible to students, researchers and engineers worldwide. Use of the program requires knowledge in the theory and procedures for seismic site response analysis and geotechnical earthquake engineering. This includes topics such as ground motions, site characterization, seismic behavior of soils and numerical modeling. Often a team effort maybe required to develop the appropriate input for the analysis, and to interpret analysis results. It is suggested that the user reviews relevant literature and seek appropriate expertise in developing input of the analysis and interpretation of the results.
The following complementary analyses are recommended when using RSSeismic:
- For every finite element–based effective stress analysis, perform a nonlinear total stress analysis using the lumped mass model.
- For every nonlinear lumped mass analysis, perform an equivalent linear analysis.
RSSeismic enables users to perform these complementary analyses using the same soil profile, eliminating the need for separate profile development or additional model setup.
How to get started with RSSeismic
The RSSeismic program has been laid out in a series of workflow tabs to guide each user through the recommended workflow for setting up and analyzing their soil profile(s). These tabs include:
