This special issue is dedicated to the Memory of Professor Stephen A. Mahin, a world-renowned expert in earthquake engineering whose visionary research and educational efforts and contributions bridged theory, numerical modeling and computer simulation, experiments, field testing and reconnaissance work, and design. His decades of outstanding, prolific, enthusiastic, sustained and selfless service to the academia, profession and industry as well as his friendship will be remembered forever. In his capacity as Director of the Pacific Earthquake Engineering Research (PEER) Center (2009-2015), Steve was steadfast in supporting the development of OpenSees.
OpenSees (Open System for Earthquake Engineering Simulation) is an open source object-oriented finite element (FE) software framework for modeling structural and geotechnical systems and simulate their response to static and dynamic loads, with particular emphasis to earthquakes. This framework has been under development by the PEER Center since 1997 with the National Science Foundation (NSF) as a main source of funding. OpenSees supports a wide range of simulation models, solution procedures, distributed computing models, and high-end computing. It allows the integration of advanced models of structures and soils to investigate challenging problems in soil-foundation-structure interaction. It has very attractive capabilities for physical parameterization of SSI models, response sensitivity analysis, probabilistic modeling and reliability analysis.
Over the past two decades, OpenSees has continuously integrated the latest research outcomes (e.g, element and material models, numerical methods, nonlinear solution strategies) from researchers and engineers across the world. OpenSees has become one of the most powerful open-source research and development tool through which users can implement and test new ideas and concepts more easily and faster than before. With this background in mind, this special issue mainly focuses on (but is not limited to) the wide-spread applications and developments in OpenSees in the civil engineering community, including:
1. Nonlinear FE modeling and analysis methods for structural, geotechnical or soil-foundation-structural or systems.
2. Response analyses of structural, geotechnical or soil-foundation-structural systems subjected to earthquake or other extreme loading conditions.
3. Probabilistic and deterministic analysis methods.
4. Comparison between experimental/field measurements and FE prediction results.
5. Integration of high performance numerical and experimental simulations methods.
6. Other applications of mechanics to civil engineering
The development and implementation of new analytical models, novel computational methods, hybrid experimental-numerical methods and experimental-analytical correlation studies are particularly welcome.
