II-DAP: Interactive Interface for Dynamic Analysis Procedures

IIDAP is a standalone MATLAB-based program that was first developed in 2018 at the Resilient Steel Structures Laboratory (RESSLAB) in Ecole Polytechnique Federale de Lausanne (EPFL), Switzerland. With 10K+ lines of code IIDAP is capable of performing a variety of dynamic analysis procedures ranging from simple response history analysis to response spectrum and incremental dynamic analyses on single degree-of-freedom systems (SDoF). IIDAP includes a wide-ranging library of SDoF system models ranging from simple non-deteriorating linear and bilinear models to state-of-the-art deteriorating bilinear pinched
 and peak-oriented responses. A seismic hazard module is also included for the quantification of collapse risk. IIDAP is highly beneficial for both educational and research purposes.
