- BridgePBEE: An Integrated Software Platform for PBEE of Bridge Systems
BridgePBEE (Website: http://peer.berkeley.edu/bridgepbee) is a graphical user interface (GUI) being developed to combine nonlinear dynamic time history analysis of coupled soil-structure systems with an implementation of performance-based earthquake engineering (PBEE). The user interface builds upon previous code that allowed for analysis of piles in a soil domain under nonlinear static and nonlinear dynamic loads (OpenSeesPL). Functionality was extended for analysis of multiple suites of ground motions and combination of results probabilistically using the PBEE framework developed by PEER.
- OpenSeesPL: A 3D Simulation Environment for Seismic & Pushover Analysis of Lateral Pile-Ground Interaction
OpenSeesPL (Website: http://cyclic.ucsd.edu/OpenSeesPL) is a graphical user interface (GUI) for three dimensional (3D) ground and ground-structure response. The OpenSees Finite Element Computational Analysis framework (http://opensees.berkeley.edu) is employed to conduct all analyses. The OpenSeesPL graphical interface (pre- and post-processor) is focused on facilitating a wide class of 3D studies (with additional capabilities yet under development).
- Cyclic1D: 1D Simulation of Site Earthquake Response and Liquefaction
Cyclic 1D (Website: http://cyclic.ucsd.edu) is an Internet-based nonlinear Finite Element program for execution of one-dimensional site amplification and liquefaction simulations (for level as well as mildly inclined sites).
- CyclicTP: A 2D Simulation Environment for Seismic Analysis of Shallow Foundation
CyclicTP (Website: http://cyclic.ucsd.edu/CyclicTP) is intended primarily as an analysis tool for surface loads on saturated ground, under liquefaction-induced seismic excitation scenarios. Excitation is prescribed along the mesh base as total dynamic lateral motion. The lateral mesh borders undergo shear-beam type motions (equal motion of lateral boundaries is enforced). The program allows execution of linear analysis (with viscous damping) to allow users more basic insight, beforce exercising the plasticity-based nonlinear soil compatibilities. It is advisable to start with this option, and gradually increase the level of seismic excitation so as to gradually track changes.
- CyclicED: A 2D Simulation Environment for Seismic Analysis of Earth Dams
CyclicED (Website: http://cyclic.ucsd.edu/CyclicED) is intended primarily as an analysis tool for earth dams, under liquefaction-induced seismic excitation scenarios. Excitation is prescribed along the mesh base as total dynamic lateral motion. The lateral mesh borders undergo shear-beam type motions. The program allows execution of linear analysis as well as the plasticity-based nonlinear soil analysis.
