New earthquake-engineering software DYANAS is available, developed within the activities of the ReLUIS project at the University of Naples Federico II. DYANAS is a MATHWORKS MATLAB®-based graphical user interface that uses the OpenSees finite element platform to perform nonlinear dynamic analysis of single-degree-of-freedom (SDOF) oscillators. The scope of this free, open-source software is to serve as a tool for performance-based earthquake engineering research.
