OpenSees (Open System for Earthquake Engineering Simulation) is an advanced, open-source software framework designed to simulate the seismic response of structural and geotechnical systems. Developed by the Pacific Earthquake Engineering Research Center with support from the National Science Foundation, it aims to enhance earthquake engineering through improved modeling and computational simulation. The software and additional resources are available on the OpenSees website.
Key features of OpenSees include:
1. Giving the opportunity of Beam-Column and Continuum Elements it supports a variety of elements for structural and geotechnical modeling.
2. Offers diverse material models for beam-columns.
3. It provides comprehensive algorithms and methods for nonlinear static and dynamic analysis, including equation solvers and constraint handling.
4. It has been designed for scalable simulations on high-end computers, allowing extensive parameter studies.
5. It uses object-oriented methodologies for flexibility, combining various models, solution methods, and data processing procedures.
6. It adapts to solve complex nonlinear problems under static and dynamic loads.
7. The software facilitates model definition, solution procedures, and post-processing for simple to complex systems.
8. It is compatible with desktop PCs and parallel computers, leveraging high-end computing resources.
