OpenSees Days 2nd Italian Conference

OpenSees Days Italy
2nd Conference
Salerno, Italy, 10-11 June 2015
It is with great pleasure that we introduce this volume of proceedings of the second OpenSees Days Italy, held in Salerno on 10 and 11 June 2015.
The first OpenSees Days were held in 2012 in Rome, where several scientists gathered to share their experience in using OpenSees in their research. In that occasion, the attendance was mainly from Italy and from some other European countries. In this new edition of the OpenSees Days we also have the participation of researchers from China and Iran, whom we warmly welcome.
The Scientific Committee has worked with enthusiasm to organize this event and we are proud to see that the number of papers has increased, as well as the active participation of both scientists and professionals, also thanks to the support of the University of Salerno and to the Chamber of Engineers of Salerno. All of our appreciation goes to these two fundamental Institutions.
Based on the topic, papers were presented in four different sessions and the chapters of this volume follow the same arrangement (in parenthesis the number of papers): Case Studies (3), Modeling and New Elements (7), Nonlinear Analysis (14), and Structural Reliability and Durability (6).
In between the presentations, the audience had the opportunity to listen to four highly appreciated keynote speeches. The keynote speakers, whom we warmheartedly thank for the interest raised by their innovative topics were: 
Thomas Hsu: Cyclic Test of a Large Cylindrical RC Containment Vessel and its FEA Simulation using OpenSees,
Xinzheng Lu: Development and application of OpenSees for large-scale structures,
Frank McKenna: OpenSees: Past, Present and Future Challenges,
Asif Usmani: Challenges of Simulating Structural Response to Real Fires: An OpenSees Solution.
After these two successful events, we are already at work for the next edition, which will certainly witness stimulating advances. We expect to see interesting innovative
applications in the field of civil engineering and, especially, we look forward to the development of new user interfaces, both, to assist in the implementation of new elements for research, and to simplify the use of existing elements for modeling and analysis of structures.
